A_FGTR2-_3T: An infrared absorption spectroscope can be used to determine accurately
the concentrations of free and associated molecules in solutions and to
find the equilibrium constant K for the reaction of formation of
ky-drogen bonds. The temperature dependence of the equilibrium constait
can be used to determine the energy of the reaction and hence the energy
of the hydrogen bond. The present authors discuss theoretical
Jetarminatioa.ef the equilibrium constant K and the integral absorption
coefficients Ek of the molecules which make up the associated complex
(formed by faeans of a hydrogen bond between a molecule of the solvent
and a molecule of the solute). The discussion deals with the case when
the absorption bands of the mono-.liar and the complex are overlapping.

experimental results described by Lord and his co-workers (Ref 61 leads
to considerable errors. A better method of determinAtion of K and Sk is
described; this method uses the least-squarastechnique. The paper is
entirely theoretical. Acknowledgment is made to Prof. VAF-. Clmlano,7skiy

bombardment the radiation from the short-life disintegration is 0 times as intense
as that for the half life of 3 hrs. The short-life radiation is also harder. It is
suggested that the half-life period of 3hrs. is due to SiR formed by neutron caDture
of P with the emission Qf a proton, in agreement with Fermi, while the half-life period
of 3 min. is due to A126 formed by neutron capture of P with the emission of an a-
rarticle. Morris Muskat

and A. Vibe. Compt. rend. dead. sci. U.R.S.S. 3, 226-7 (in English 228-9) (1934).-
In addn. to the half-life period of 12 min. previously reported by Fermi for the
radioactive element formed by the neutron bombardment of Al, there is an intense
radiation with a half life of over 12 hrs. The 12-min. radiation is also accompanied
by a radiation, of the same half life, with intensity corresponding to on~ quantum
for each 4ecompu. Chem. tests show the 12-min. period element to be RaMg 7 rather
than RaNa24. The latter nrobably gives the 12-hr. disintegration. M. M.

Shchnkin and A. Vibe. Compt. rend. acad. sci. U.R. S. 3- 3, 422-3 (in English
423-4) (1934).- Al bombarded with neutrons gives 2 radioactive products, one with a short
and one with a very long period. The half-decompn. period for the latter product is about
12 ~rs. The initial intensity of the -radiation from both products is the same. The
counter throws decreased only from 120 to 90 per min. when 5.4 mm. of Pb was used for a
screen for the long-period product. This long-period product is shown to be radioactive
Na. When an ~l nucleus wtures a neutron these 2 reactions occur: A127 n1 = Ra-mle7
H1 and p_127 nl Ra-Na2 He4. It is su
,ggested that the decompns. might occur as
follows: Ra-Na24 ~jg24 e hvl; Ra-Na24 = Na23 nl hv. H. A. Smith

ABSTRACT: The constructed apparatus, which shall be able to separate clear-
ly isotorpes even with a relative mass difference of 1/240, must
have a high dispersion, a high resolving power and especially well
stabilized magnetical andelectrical fields. An axial-sy:ametrical
field, the dispersion of whiich is proportional to the square of
the focusing angle, was used as a magnetic field. The focusing
angle is 2250. The measured dispersion of the apparatus amounts
to 2o mm. at a relative mass difference of the masses to be se-
parated of 1~-
The stabilization of the ma.-netic field of the separating device
has been brought to 0,005% by the aid of a valve scheme.The ac-
c,-,lcration velocity for the source of ions (up to ~,o kV) is sta-
bilized by a double cascade scheme up to O,ol%. But also the
current in the discharge source of ions is stabilized. The vacuum

ABSTRACT.~, This article is )f a lecture delivered at
the 9. All.-Union Ck)nj;re:,.-, cf Nuclear Spectroscopy (Kharlkov,
January 1959). The spectrometer developed belongs to the
n-ff-type, in which., for the purpose of improving light in-,
tensity accompanied by a high degree of resolving power, the
radius of the central orbit was consilerably enlarged (155 cm).
The magnet has the shape of a mushroom and is composed of
3 parts~ the core, a cylindrical part, and 2 "hats" (photo.,
graph attached), The width of -~he poles is - 110 cm, the dis-
tance between them is 35 cm, and the total weight is 90 t.
Profiled end pieces are fastened to the pole shoes, their
form is calculated by means of an analytical method. The
operation chamber has a content of ,1000 1. Evacuation is.
brought about by means of a VIT-12 forepump- As a high-vacuum
pump a VH-5 9- type unit is used. The operating vacuum amounts
Card 1/3 to some 10" torr.. It is possible to measure 4 a-active pre-

details are given in the connection. Fig. 5 shows a scheme of the system,
briefly discussed, for the stabilization of the magnetic field. The
H-measurement is carried out by means of the paramagnetic proton
resonance, A 0-5/o aqueous solution of manganese chloride was used for
transmission.. The solution filled in a vacuum pocket was directly placed
in the magnet gap. The block diagram of the field meter is discussed and
shown in Fig. 6. The error of this meter amounts to j..10-5. The investiga-
tion of the magnetic field topography is discussed next, For this purpose
two devices were developed, one basing on the signal measurement by means
of a ballistic galvanometer, the other basing on a signal compensation,
Both devices were very sensitive (-0.05 oe/mm), Results may be seen in ~c
Fig- 8 and in a table. More accurate data will be supplied in another
paper. Finally the ion-optical properties of this device are discussed.
Fig. 9 shows the shape of the focal surface. The energy range AE/E 0 of the
a-particles wasvlO% and was simultaneously recorded by photographic
plates- The half-width of the lines within the whole range, was r-0.07. The
dispersion dE/dx was,4,,2.28-10-4EO/mm~ This comes up to-,/1.2 kev mm- 1 for
Po 210 a-particles. The resolving power of the device is illustrated by the

topes was found tobe 12.24 mm. A theoretical maximum resolution is 250,000; in Pra
however, the resolution was under 100Dfor PbSO4 isotope separation. A pbR04
sample isolated by the above mass separator had these concentrations: CgbXO4

contamination of the sample by the natural mixture of Pb isotopes at the separator
emitter, the sample must have contained 99.993~ Pb204, which corresponds to an
enrichment ratio of 700,000. A sample of cadmium enriched in the mass separator
contained 99.9~,14 Cd&14. "In conclusion, the authors wish to thank L. k ISO

TTTLE: On the Problem of Ion Formation at the Maximum of Electronic Density
of the F2-Layer
P&RIODICAL: Tr. Sibirsk. fiz.-tekhn. in-ta pri Tomskom -an-te, 1959, No. 37,
pp. 49-56 X
TE)P-- The problem of the relative position of the levels of maxiarum elec-
tron density hm and maximum ionformation h, is of great importance for the study
of the ionozation dynamics of the F2-layer, The diurnal course of the magnitude
of the difference h--hj is estimated for the summer season at Irkutsk for average
median hPF2 for 19118-1960 and 1951-1954 under the assumption that h, coincides wiih
h, in morning when a sharp decrease of the altitude hm and a rapid Licrease in

On the Problem of Ion Formation at the Maximum of Electronic Density cf the
F2-Layer
The recombination coeffidents at the hm level are calculated from the obtained
values of I/Io and the given value of Io. The obtained differences hm - h,
permitted the estimation of magnitude and speed direction of the verti2al drift
v of the electronion gas under defined assumptions; the calculations ire carried
out with the Martin formulae with respect to the observations in the z-nmer season
at Irkutsk. For the value d%A3 z 1. 10-10, the drift speed has a ma-timum and
is directed upwards at 07 o1clock of local time, and a maximum with thu direction
downwards at 18 o'clock; the minimum speed takes place by about midday and about
midnight. The maximum value is v -,/ 10 and 14 m/sec respectively, for years near
to th-= maximum (1948 - 1950) and the minimum (1951 - 1954) of solar activity.
By day is v -5 m/se,- and changes in direction at about midday.

ABSTRACT: The latitude variation has been studied as a condition for the F1 layer
occurrence during high solar activity. The frequency of observations is denoted by
V and monthly observations are slimmed up by the chaxacteristic parameter
S
Cord 111~r -2-

ACCESSION NR: AP4001828
Plots are given for S and r as a function of the latitude from data accinulated
during the 1957-59 period, (r = Sclear/S). The probability of an F1 layer occur-
rence at low solar altitudes from the horizon is 9hown to increase by an increase
in latitude. The cosine of the solar zenith angle decreases with an increase in
latitude, and a ma imum value of this parameter is observed at latitude 200 in the
summer hemisphere. It is shown that this latitude dependence of F1 may be due to
the ratio n,2/nj and n2/n, on the minimum level of the function Fiz (ratio of
molecular nitrogen to atomic oxygen). This function is related approximately to
the cosine of the solar zenith angle cos x12-ol/f(xi)

ABSTRACT: The same aithor in another paper 133 estimated the rate of ion forma-
tion at heights from 150 to 300 km in the 180-911-A spectral range, using
data collected by G. M. Nikol'skiy on the intensity of solar-ionizing radia-
tion during high activity. The model of the atmosphere used by the -author
and the intensity of ionizing radiation were selected for conditions of
maximum solar activity. Both the model of the atmsophere developed by
Shchepkin and the values obtained for the,.rate of ion formation are then
used to estimate electron concentrations"Ifor cases involving different
rates of ion-exchange and dissociative recombination reactions. In the

molecular nitrogen, atomic oxygen, and molecular oxygen. The density and
molecular weight of the model atmosphere are taken front the U. S. Standard
Atmosphere, 1962. Computations show that the rate of ion,formation of 0+
has a maximum at 180 km, while the rates of the other components reach their

ABSTRACT: 'L. A. Shchepkin [21 has investigated the latitudinal and cyclical
conditions associated with the appearance of the F, layer during periods of
high solar activity. Tile cosine of the zenith angle of the sun (cos x),
characterizing the onset and end of the regular appearance of the F, layer
at noon, is used as an index of the conditions of F, layer appearance. The.
author then plots the cos x values against the Wolf number for sunspot
appearance. 'A direct correlation is found to exist between the cos x
values and the mean monthly sunspot numbers. The value of cos x is also
seen to decrease with latitude, indicating that the conditions for the for-
mation of the F, layer improve with an increase in latitude. ' The authorthanks

ABSTRACT: An experimental method for determining the error signal probability den-
sity and correlation coefficient caused by fluctuation noise in a phase-lock frequezA~.Y;
I control system is described. An experimental set-up measures error signal distri-
bution, occurrence frequency of phase jitter, the mean fluctuation frequency of the
error signal, and jitter time duration. A digital phase meter with linear character-~
i istics of -n-+n radians with a recorder of random Dhase disturbance is part of the
setup; it consists of a delay circuit, a sawtooth 7enerator, and an oscillograpn.
The delay circuit, driven by ptLlses derived from areference oscillator, controls
the input to the sawtooth generator. The output of the sa,,rtooth generator is fed to
the vertical input of the oscillograph. A second output from the reference oscilla-
tor is fed into the horizontal input of the oscillograph through the phase-lock
system and a pulse-shaping circuit. The error sLFnal is displayed on the oscillo-

ABSTRACT,, The author disctisse,~,z briefly the properties, advaiitage3
and possible applications of baritim-oxide ferrite
(approximately BaO. 6Fe203) magnets. Ifer own experiments
were carried out with magnets prepared from a mixture of
barium nitrate with iron nitrate or ferric oxide (grade
ChDA). The mixture was briquetted and calcined at 1160*C~.
the briquettes being ground. Size grading of the powder
was difficult to control(mainly because of adhesion of
particles below 20 microns) but had an important effect on
the properties of the magnets made by sintering the powder
mixed with paraffin at 1140 to 1220*C. The magnetic
properties in relation to sintering temperature, grinding
time and chemical composition are tabulated in Tables 1,
2 and 3 respectively. To improve the low remanence of
the oxide magnets,sintering at 1200 to 1260*C in a magnetic
field was tried in a special apparatus (Fig 1).

J-LE-~ T~, Effect of Flight Velocity of a Space Vehicle on
the Error of an Inertial Navigation System A

IBSTRACT- At ultrasonic flight velocities the rate of rotation of
a spa!~e vehicle with respect to the center of the earth
reaches appreciable magnitudes and may exceed by a factor
of 10 or 12 the angular velocity of revolution of the
earth. This angular velocity causes appreciable
vi-,Ariati.on of' the err-ors of an inertial navigation system
arid gives ri5e to interaction between the motions of
the spa--p vehicle in -Ehe lateval and longitudinal
Jire~-t.ions. The system considered is purely inertial in
which the stabLlized plane should remain parallel to the
plane of the true horizon during the entire time of
flight, It is assumed that flight occurs over the arc of
a great circle of variable radius (variable height of
flight) and the direction of flight coincides with the
Card 1/4 direction of one of the axes of the stabilized plane, Vr

rhe Effect of Fltgrht Velocity of a Space Vehicle on the Error of

Schuler period, These osci-1latxons are superimposed on
-An aperiodic mot-i-on. It is found that the lateral error
loi a given forward velocity depends on the error in the
Initial lateral vetocity and the initial adjustment of
the platform in the longitudinal and vertical directions
and on the deviations of the pitch and azimuth gyroscopes.
Calculations show that the last factor is the most
impcr~ant, The error in the longitudinal direction
Witifigyroscope deviation 0,50/hr is the most important.
With better stabilization, the initial errors in the
vertical and longitudinal velocities become decisive.
The component of longitudinal error due to the initial
er-ror in the vertical velocity exceeds the other sources
of er-ror with -velo.~iti-es " r- km/sec. The initial error
of the longitudinal velocity is fairly strongly expressed
at all flight velocities. It is therefore necessary to
maintain a given value of longitudinal flight velocity to
a high degree of prezision. In all cases the errors
C'Ira V4 decrease wi-th increase of velocity. Acknowledgments
