ABSTRACT: In resonance scattering of modulated light by atoms whose excited state
is a Zeeman triplet, the depth of modulation ofthe luminescence is resonance-de-
pendent on the splitting magnetic field; the degree of modulation exhibits a maxi-
mum when the modulation frequency agrees with the frequency of the sigma component
of the line. On the other hand, In scattering of light of constant intensity (non-U
modulated), one can obtain ;Dodulated luminescence by applyingp in addition to the
constant splitting magnetic field, an alternating field perpendicular or parallel

to the constant one. In the former case there obtains "double resonance"; in the
latter case, "parametric resonance". Modulation frequency conversion incident to
parametric and double resonance is discussed and analyzed theoretically; the dis-
cussion is based on earlier publications of the authors. It is shown that incident:

of the incident light modulation and field modulation, but also with combination
frequencies. The amplitude of the combination harmonics is resonance-dependent on
the strength of the constant field. The experimental part of the study was carried:
out on a set-up consisting of an oscillator f0eding a coil via an rf amplifier, a
photomultiplier, a tuned amplifier and a detector assembly. The set-up was similar
to that described earlier by the authors ME iTF,45,503,1963). Radiation associated
with the 53Pl__51S
0 transition in cadmium vapor (contained in a tube surrounded by
the above-mentioned coil) was observed. The1purpose of the experiments was not to
obtain detailed data, but only to demonstrat,,the feasibility of modulation frequen-
cy conversion. A modulation amplitude verstW!field strength curve is reproduced. - -- .:

ABSTRACT: In a series of recent papers by one of the authors (Yo.B.Aleksandrov),
alone and in collatioration with othor investigators (Opt.i spol-tr.14,436,1963; Zh-
ETr-,45,503,1953; Opt.i spektr.16,377,1964; lbid.16,193,1964) there were described
experiments in which there was observed beating of the radiation from a system of
atoms characterized by close sublevels in the excited state. The beats arise as a
result of interference of states. The theory of the phenomenon as regards opticil
excitation was developed by O.V.Konstantinov and V.I.Perel' (Opt.i spelttr.16,193,
1064; ZhETF 45,279,1963) using the density matrix formallfsm. In the present paper
there is proposed a simpler variant of the theory, which is applicable for diffe-

rent types and ranges of e%citation and, in the opinion of the authors, is more
physically meaningful. The approach is based on the assumptions that lifetimes of
the atoms in the-energetically close excited states are equal, that there is a cer-
ta-in probability for excitation of the atoms to the states 1 and 2 with a definite
phase and amplitude relation (coherent excitation) and that the effective excita-
tion time is much shorter than the lifetime in the excited states. Thus, there are
derived formulas characterizing the luminescence beats under conditions of modula-
tion of the excitation or of the separation between excited sublevels. Beats should
also occur in the case of modulation in phase, rapid rotation of the plane of po-
larization, etc. "We are indebted to O.V.Konstantinov and V.I.Perel' for discus-
sion of the work and critical remarks.'I Orig.art.has: 12 formulas.

ABSTRACT: The author describes the realization of a new methlod of synchronizing in-
tensity beats,in the spontaneous radiation of atoms. The metbod was originally pro-
posed in an earlir.,r paper by the author (with V. P. Kozlov, Opt. i spektr. v. 16, 533
with correction in v. 16, 1068.9 1964) and consists in making -the elementary process
that rroduces the beats govern the initial phase of the beat. The experiment is base
on the cadmium intercombination transition 53P,--5'So in a magnetic field. Cadmium
vapor at 220C is escited by 3261 A resonance radiation from a cadmium lampp directed
along the magnetic field and linearly polarized (Fig. 1). The luminescence is ob-
.served at right angles to the field by means of a photomultiplier. The modulation ofl
the initial phase was produced by oscillating the plane of polariza -on at high fre-
quency with the aid of the Faraday effect in the same eadm ear the absorp-r
ium
tion line. Details of the oscillation of the plane of polarization are described in
a companion jxLper in the same source (Opt. i spektr. v. 19, 4-55, 1965, Ace. AP5022873Y-

ABSTRACT- Ibis is a companion to the preceding paper in the same source (Opt. i vv,sj.
spektr. v. 19, 452, 1965, Ace. AP5022872) and describes the use of the Faraday effect'
in cadmium vapor to modulate and filter out the unshifted resonance lines. The pur-
pose.of the experiment was to develop a technique which can be useful in certain ex-
periments with resonance excitation. The experiment was performed with the cadmium
3261 A r9sonance line. Lihearly polarized light from the cadmium lamp passed through
a_qMartzVcel1 placed together with an electric oven inside a coreless coil to provide
a magnetic field up to 2000 gauss directed along the light lbeam. The magnetle,field
split the excited state of cadmium 53P, into a simple Zeeman triplet whose outer com-
ponents pr-pduced the magnetic rotation and absorption. MaxLmum differential rotationf-
of the plane of polarization could be obtained by varying the splitting and the vapors
density under the given experimental conditions, and by eboi5sing the optimum tempera-~

ABSTRACT: The authors investigate theoretically and experimentally
a new method.of orienting gas atoms in a magnetic field perpendicu-
lar Ito an orienting light beam. This is done by using an alternat-
I.ing magnetic field in addition to a constant one, and modulating
the alternating field while maintaining the beam intensity constant.
It is shown theoretically that if the alternating field makes a-

-small angle with the constant field, then the resultant moment
precesses about the constant field and produces large constant com-
ponents of the magnetic moment in the directions of the magnetic
field and of the light. The theory of the process is briefly devel-
oped and expressions are derived for the total moment and its pro-
jections. To check, on the theory, experiments were made on the dc
and ac components of the moment projections on the light beam and
on the constant field in the vicinity of the first resonance., The
experiments were made with a mixturelof cesium vapor and argon,
using an orienting beam which was circularly polarized and contained
only one long-wave component of the resonant doublet. A cesium
electrodeless discharge spherical lamp served as the source. The
experiment setup is described. The test results are found to be in
isatisfactory agreement with the theory. Plots were obtained of the

ABSTRACT: The stimulated Raman scattering was investigated at an excitation power
just above the threihold using the following three different setups: 1), a Raman
cell in the resonator of a laser; 2) a longitudinal selective resonator (the term
used by the authors for the case when the Raman laser - Wator is in the direction
of the ruby laser resonator); aM 3)a transverse selectiv Tesonator (the term used for
the case when the/Raman laser resonator is rotated 90* from the direction of the
axis of the rubyNlaser, i.e., a 90* off-axis Raman laser resonator). In the first
setup the gi7a_ntpulses were produced by a ruby crystal. Using two variable-trans-
mission-coefficient filters (transmission coefficient 30-50% at X - 694 mv) the
effective intensity of the 30-300 nsec-duration pulses in the resonator reached
100 Mwt/CM2. The maximum energy per pulse was 3-4 J. Two dielectric mirrors writh

SRS line in benzene), 40% at A 805 mu (first harmonic) and 70% at A 875 m
(second harmonic) were used in the experiments. The SRS in benzene had thresholds
for a specified length of the Raman cell (i) and the laser input power. No SRS
was observed at I < 2; however, SRS.was stable for 5 < 1 < 60 cm. The threshold
power decreased almost linearly with increasing 1. At 1 w 60 cm the of ficiency of
energy conversion reached 10% of. the puwer An the cavity. It - -.4as observed that
an.increase in thielenergy'of theLpulSes from the ruby 1.5-2 times above the :L
threshold resulted in a three-order:inerease in SRS. InLthe longitudinal selective
setup, the additional reflector betweentbe ruby rod.and the Ram."Lcell had a tranS_L
missionLCoefficient of 90% at--A - 694 mp, 10%,at X - 745 V, and 1% at A 805 and
875 mv. In this mode of operation the efficiency of energy conversion was at least
as high as that in the previous case. Two higher harmonics at A = 745 and 805 mp
which reached saturation at ulo% of the input power were observed. Results similar
to those of the
longibidina--setupl.Fere achieved with a transverse selectivesetup. HY.Never,
SRS was achieved in a Raman cell the length of which along the laser beam was only
I cm~ Stimulated Brillouin scattering in benzene was also observed in this setup.

ABSTRACT: The stimulated Raman scattering was investigated at an excitation power
just above the threshold using the following three different setups: 1) a Raman
cell in the resonator of a laser; 2) a longitudinal 8 ive resonator [the term
used by the for the case vhen the Raman lase donator is in the direction

for the case when the Raman laser resonator is rotated 900 from the direction of the
axis ofthe ruby laser, i.e., a 900 off-axis Raman laser resonator] (see Fig. 1).
In the,first setup (Fig. la) the giant pulses were produced by- a ruby crystal 10 to
12 cm long and 12-16 mm in diameter. With two variable-.transmission-coefficient
filters (transmission coefficient 10-80% at A 6943 the effective intensity of

the 20-200' nsec-duration pulses in the resonator reached 100 Mwt/cm2. The maximum
~energy per'pulse was 5-6 J. Two dielectric mirrors 01 and 02 with a transmission
coefficient of O.h% at A 694 mu, 0.8% at A = 7h5 mu (the fundamental SRS line in
benzene), and 40% at A = 805 mu (the first harmonic) were used in the experiments.
The sensitivity of the detectors was sufficient to register 10-4 of the energy of the
laser pulse. The setul~? shown in Fig.Ila was used to investigate SRS in benzene. It
was observed that an increase in the energy of the pulses from the ruby laser 1.5-2
times above the threshold resulted in a three-order increase in SRS at the funda-
mental frequency. Saturation was reached when the intensity of SRS was about 10% of
the energy input, at which time the second harmonic whose energy output quickly
reached the level of SRS at the fundamental frequency (at saturation), appeared.
When the second harmonic reached saturation the duration and the intensity of the
laser pulses decreased sharply due to the reverse effect of SRS on the ruby laser
pulses. When the length of the Raman cell ~1) was increased, the threshold power
and the pulse energy required to achieve SRS decreased. Also, the larger the cell,
the sm ller the energy above the threshold at which second harmonics were generated.
The SRS was stable when 1 was between 5 and 60 cm. In the longitudinal selective
setup (Fig. lb) reflector 02-replaced 04 and the transmisslon coefficient Of 03 was
very high at A = 694 mp and was at a minimum at A = 745 mg. The gain of SRS at
1 = 5, 20, and 60 cm was at least.as high as in the previoras case, although the pump
Dover and the pulse energy required were considerably smalLer. For example, when the
output of a ruby laser pulse of 30 nsec duration was h0 Mw (1 = 20 cm) three 10 Mw
SRS pulses of 20 nsee duration were observed in the Raman laser cell. Similar re-

ABSTRACT: The method ofAmeasuring, the modulus and direction of the
vector of force of weak ih!15netic fields, based on the optic orien-
tation of atoms, is c aracterIzed by tne fact that the effect of the
action of the measured magnetic field and of the known light intensity
on the paramagnetic atoms is compared and the magnetic field strenSth
is determined by the intensity of the orienting light. These charac-
teristics are incorporated in order to widen the measurement rar.,re ol'
weak magnetic fields.

ABSTRACT: The authors experimentally investigated the frequency shift of the optical
resonant transitiqn 4S1/2 - 4PJ/2 3/2 of potassium (principal doublet). It can be
be shown that the~expected freque-Acy shift of this transition is connected princ
ipallyi
'with virtual transition induced by the laser pulse from the ground level (01/2
4PI 2,3/2) and th~ excited level (4P3/2 - 6S1/2). The first pair of transitions is
sti~lsufficiently far from the resonances (the transition wavelengths are 7665 and
17699 A, that of the laser is 6943 A). The 4P3/? - 651/2 transition is much closer
to resonance OL = 6939 X). In spite of this, all these transitions make comparable
tributions to the sought frequency shift of the investigated transition, owing to
tcz difference in the oscillator strengths. It is important that the ground and

excited levels are shifted here by the ruby-laser light in opposite directions.
In the experiment Iight from potassium lamp 1 was passed through vessel 2 with
potassium vapor saturated at 100*C (see the figure). At the selected temperature,,
the vapor absorbedabout 80% of the lamp's resonant radiation. Transmission of
light by vessel :2 was expected to increase during the action of the pulse from laser
3, provided the resultant transition frequency shift is commensurate with the line
width of the lamp iradiation (it was assumed that +.his line was broader than the
absorption line ofithe vapor). The transmission of the resonant light was recorded

P
F'~~; filters. Prelimilaary experiments have shown, however, that the laser pulsed is
1~1 accompanied by scittered radiation with spectral components lying in the region of
the registered potassium line. The authors used a *cial method of filtering the
resonant line witi the aid of the Faraday effect to combat the mechanism of radiation
occurrence. Afte,- passing through vessel 2, the light beam of the potassium. lamp
was made to pass Through an,auxiliary euvette 6 filled -with potassium vapor and place
between crossed polaraids 5. A local magnetic field of approximately 2 kOe was
applied to cuvettp 6. The magnetic field produced, besides splitting of the absorp-
tion line, strong:;radiation of the p1sne of polarization of the light, but only in
the nearest vicinity of optical resonanco. By magnetic field intensity selection,
the system was mace to transmit almost &11 the resonant line, and to absorb the
extraneous light.!- The entire apparatus behaves like a high-transmission optical
filter with a bandwidth on the'orde:z-of 0.1 cm-1. Under the conditions described,
a distinct signal was recorded, evidencing a decrease in the absorption of the
resonant light by -the potassium atoms in vessel 2 during the time of action of the
laser pulse (20 nsec); the laser operated in the monopulse mode by using bleaching
filters KS-19. To verify that the change in the light absorption was not connected
with some experim6ntal errors the authors checked: (1) that the signal vanished
when -the potassiu~i light was turned off; (2) that the signal vanished when the potas-.-
sium vapor was frozen out in vessel 2 (with the illumination on the photonrultiplier i
maintained at the'previous level); and (3) that the signal vanished when the operating'
mode or lamp 1 walt forced so as to broaden the emission line (the broadening was
confirmed by the observations). The minimum laser radiation power density. at which

ABSTRACT: Logic circuits made up of threshold elements are used as the basis for a learning
automaton. These bases were proposed by Varshavskiy in 1962. The problem of pattern re-
cognition is solved by finding the logic function wha-ch divides the sets of independent binary
variables Into two classes. Where Varshivskiy used an ideal logic circuit of threshold ele
ments, in the present work the weight factors of the input of every threshold element In the
first layer do not change durlng teaching and can accept only one of three fixed values +1, 0, -1.
With respect to this, the inputs of a threshold element di-Ade into activating (t z=+I), retarding

throughout the entire process. Every threshold element realizes the function
n
Yi =sign ~Ixi- 77 1, where ~i is the weight factor of the i-th input; x, is the value of the
binary input variable at the i-th input;," is the threshold value-, n is the number of the inputs of
the automaton and j = 1, 2, 3. ..... n. The specific advantages of this automaton are the large
volume of Information about the signal, the parallel processing principle, and the use of
distributed memory. It should be added that there are individual memory units for storing
weight factors for each threshold element. The automaton was used in 1962 for discriminating
the letters of the Russian alphabet, numbers, and various geometric figures. The methodology
for teaching the automaton Is discussed. Algorithms were used In the majority of cases. Feed-
back was discontinued and every element was checked for Its correct answer to the teaching
sequence. The teaching process was continued for those elements which gave wrong answers.
Curves are given showing the increase in the number of correct answers for the elements of the
automaton. A part of the experiment consisted of finding out whether the automat was able to
recognize new elements of the images already incorporated. This phase of the experiment was
called "checking the automaton for generalization. 11 Under these conditions 60 to 80% of the '
answers were correct. The automaton was simulated n h gh, Td digital computers when the

ABSTRACT: A water-soluble glue for use in scintillation counters, Cerenko-,l spectro-
meters, and other similar equipment has been developed. The glue provides good, uni-
form optical and mechanical contacts between photoelectric amplifiers and irradiating
or light-conducting media. The glue is made from a DEG-1 epoxial resin (a glycerin
compound) and a DEG-1 hardener. The glue maintains its consistenr--, . 40 to 60 min after
it is prepared; it requires approximately 20 hr to fully harden. It takes from sev-
eral hours to several days to dissolve the glue joints depending on their thickness,
the temperature, and rate-of-flow of water, and the surface area of' the joint that is
exposed to water. The light conducting properties of the glue have! been studied on
scintillation counters and have been found satisfactory. The authars thank Ye. S.

ABSTRACT: There are as yet no general rules about the design of
urban distribution systems. Therefore, the erection of lines
for distribution of electricity, radio and communications,
street lighting and supply to electric clocks is not co-ordinated.
Much expenditure can be saved by preparing rules for the com-
bined erection of such lines and siting them to fit in with
street gardens., It is wasteful to use columns only for street
lighting. An example of the multiple use of lighting poles is
shown in Fig.l.
Since it is now necessary to provide concrete footings for
wooden poles, the spacing of poles should be reviewed to avoid
waste. Greater use should be made of reinforced concrete in
various structures. At present the common types of transformer
mounting and distribution equipment use littlexeinforced con-
crete. Existing typical transformer-stations for general
Cardl/2 supply are somewhat extravagant and greater use should be made

ABSTRACT! In order to Investigate the resolving time of a.Gerenkov-
spectrometer~-a method of coincidence circuits was applied. A spectro-
meter (de bed in PTE 1964, no. 34, p. 38) with a 300-mm radiator was
used. The light from the radiator was collected by the FEU-49 photo-
multiplier tube. The coincidence circuit was formed by the addition of
two FEU-36 photomultipliers which had an adequate amplification factor
and a time spread not greater.than 2 nsec, By such an arrangement a
resolving ti'me of about 4 x 10-9 sec was obtained without diminishing
the 100-pot efficiency of recording the gar-ma quanta in the range from
100 to 600 Mev. After a preliminary theoretical study, the experlmenta~

were conducted and the performance of the coincidence circuit was testa.~.
The experimental curves showed that at the electron energy of 100 Mev,,
a 100-pet efficiency of recording was attained when two additional
FEU-36 photomultipliem were included in the circuit. The dependence of.,
the recording efficiency upon the resolving time was also investigated-
and the curves of "delayed".coincidehoes were plotted for electron beLm
energies of 100 and 500 Yev. In the case of 100 Mev, the best resolv-
ing time was 4.7 x*10-9 sec While at 500 Mev the 100-pot efficienoy.was
attained at about 4 x 10-9 see. The comparison of these results.with
the data published by other authors showed the superiority of the abovG
arrangement. The,authors.expressed their appreciation to Ye. M. Levkin

TEXT: The oxide of triethyl lead (I) was obtained by reaction of disperse
metallic Na with triethyl lead monohydroxide (II) in benzene. I decomposes
ato,j 200C, reacts vigorously with acetone and acetaldehyde, and reacts
instantaneously with water to form II quantitatively. When reacting with
methyl, ethyl, benzyl, and a,a-dimethyl-benzyl alcohols; as well as with
hydroperoxides of tert-butyl and cc-cumyl, I gives the corresponding oxy
and peroxy derivatives of triethyl lead, which are unstable at 1200C.
The rate of thermal decomposition of I at 70-900C without solvent was
studied. The products obtained consist of an equimolar mixture of
C2H6 and C2H4 (with an impurity of 1-1.5 % of butane), 0.97 mole of

of Pb, which is insoluble in organic solvents. The authors assume that
the accelerating effect of I on the oxidation of hexaethyl dilead by 0 2
in n-nonane solution is caused by the ability of I to decompose with
the formation of ethyl radicals, whereby a degenerate chain reaction is
effected. For Report 2 see RZC, 1961, 8Zh231-, LAbstracter's note:

TITLE: Bistriethyl-lead Oxide
PERIODICAL: Doklady Akademii nauk SSSR, 1961, Vol. 136, No. 1, pp. 89-92
TEXT: Bistriethyl-lead oxide,((C2H5)3 Pb)20, was synthesized with a view to
establishing its properties and studying it in detail. In an earlier work
the authors had found that bistriethyl-lead oxide has a marked accelerating
effect on the oxidation of hexaethyl dilead by oxygen. They assume this
effect to be due to free radicals formed by decomposition of bistriethyl-
lead oxide. Basing on their own resulte, they state that this compound has
never actually been obtained by other researche2.-s (Refs. 2-4), since
bistriethyl-lead oxide hydrolizes in alcoholic and aqueous solutions. The
authors therefore applied a different method: They dispersed metallic
sodium in n-nonane, removing the n-nonane thereafter by decanting and
distilling off, and then poured on dry benzene. To this mixture they added
a triethyl lead monohydroxide portion so calculated that sodium was well

in excess. In the course of 2-3 h triethyl lead monohydroxide was trans-
formed into bistriethyl-lead oxide which is readily soluble in benzene.
After filtering off the solid residue, and distilling off the benzene,
bistriethyl-lead oxide was obtained as mobile, faintly yellowish-green
liquid with a sharp specific smell. At room temperature, bistriethyl-lead
oxide hydrolizes to triethyl lead monohydroxide (to an extent of 98-99%).
Alcohols and tertiary alkyl- and aryl hydroperoxides act similarly to
water, transforming the bistriethyl-lead oxide to oxy- or peroxy comp _-nnd.;
of triethyl lead, besides triethyl lead monohydroxide. At temperaturc-, 0"
only -101C, several of these reactions occur at an appreciable rate. Tb:.
authors studied the effect of methyl-, ethyl- and benzyl alcohol, dimefty'J.-
phenyl carbinol, tert-butyl-and a-isopropyl phenyl hydroperoxide on
bistriethyl-lead oxide. The following compounds were obtained: ethoxy
triethyl lead, tert-o-butoxy triethyl lead, a-isopropyl-phenyl peroxy
triethyl lead, methoxy triethyl lead and a-isopropyl-phenoxy triethyl lead.
The organic oxy- and peroxy compounds of lead are unstable and decompose
gradually at room temperature in sealed ampoules, accompanied by a color-
change to redbrown. Bistriethyl-lead oxide reacts vigorously with acetone
at room temperature, under formation of triethyl lead monohydroxide. In

was noz further investigated were formed. On heating, bistriethyl-lead
oxide decomposes comparatively rapidl with liberation of an equimolecular
mixture of ethane and ethylenet and 1~ butane. The residue is tetraethyl
lead (Ref. 7). There-are 2 figures, 1 table, and 7 references: 2 Soviet,

TEXTs Since peroxides of the type R nMOOMRn (R - hydrocarbon radical,
M - metal) are only known for Cdt Si, and Go, the authors investigated the
triethyl tin peroxide (TETP) synthesized by them, (C 2R5)3 SnOOSn(C2H 5)3' The
synthesis was carried out by mixing equimolar amounts of triethyl tin oxide
and anhydrous H,O,, dissolved in absolute ethyl ether, in the presence of
anhydrous sodium sulfate. After 10 - 15 min vigorous shaking, the mixture
was filtered, and a new portion of sodium sulfate was added to the filtrate .
After distilling off the ether at reduced pressure and room temperature, a
small amount of hexane was added, and shaken for another 2 - 3 minutes.
After filtering off the sodium sulfate, hexane was distilled off. The
residue was a viscous, golden-yellow liquid, pure TETP (100-101 % active

This reaction was used to determine the active oxygen by means of
permanganatometrio titration. TETP is ver~Cunstable and decomposes
completely within 24 hr at approximately 0 - At 600C, decomposition
proceeds most vigorously in a sealed glass phial; an explosion occurs
after 2-3min. In n-nonane solution, this reaction Is much slower. It can
be described by a kinetic reactipn equation of first order. During the
reaction, a white deposit is precipitated from the solution. It is
unBoluble in ordinary organic solvents and was identified as Aiethyl tin
oxide. A second product of thermal decomposition, ethoxy triethyl tin
(boiling point 190-1950C), remained in the solution. It can be hydrolyzed
with water, thus forming triethyl tin monohydroxide. From 1 mole of TETP,
0.93 moles of diethyl tin oxide, and 0.98 moles of ethoxy triethyl tin are
formed. The apparent activation energy of TETP decomposition in n-nonane
is 14 kcal. Polymerization of methyl methacrylate and acrylonitriie is
