Of 410 cm were used to study the intrinsic recombination radiation.
A p-n junction of '_O.I cm2was produced by diffusion -of Zn or Cd in-to the
InAs plate. The nonequilibrium carriers were excited by pulsed
injection through the junction. The radiation was observed in parallel
t.o the p-n junction plane. At 77 OK the emission spectrum has a narrow
peak -,.t 1.47 ev (optical self-absorption edge) and two maxima at lower,
energies which are in connection with recombination via impurity levels.
One of these levels is 0.2 ev distant from the middle of the forbidden
b"nd, the other 0.25 ev from a band edge. The relative height of all
maxima depends on the current density through the-p-n junction. At less

TITLE. Field effect and photoconductivity in lead-sulfide layers
PERIODICAL: Fizika tverdogo tela, v. 4, no. 5, 1962, 1174 - 1179
TE'XT: The field effect of light-sensitive PbS layers condensed on glass
and mica in vacuo is studied. An a-c method was used to measure the
dependence of conductivity on the field strength under quasi-equilibrium
conditions at room temperature. It is assumed that the conductivity of
the layer is mainly due to its particles contacting the backing. In the
range of 16 - 100 cycles, the oscillograms were independent of,the
frequency of the modulating field. Illumination of the layer increases
the number of surface holes, shortens the relaxation time T of the
f.e.
field effect, and sli.-htly increases the h-f value A'hf of the effective
mobility. If, in the absence of a field, the surface conductivity is of
the p-type, illumination shifts the curve of the field effect slightly to'i
the left, whereas a considerable shift occurs with n-type conductivity.

The real part Re p eff = ~le'f of effective mobility changes signs in some
specimens, but is always positive at high frequencies. The reduced con-
ductivity remained constant for several days when d-G voltages of up to
1500 v -.,,ere applied. Photoelectrons are trapped in the surface layer of
the photoresistors investigated. When an inversion layer appears on the
surface, the minimum of the curve representing the field effect is shifted.

ABSTRACT: The authors investigate the recombination radiation of germanium allo3~ed

emission spectra was described in an earlier paper (FTT v. T) 3339, 1965). The ratio'
of the densities in the n- and p-regions of the diodes was such that the injection

at liquid-nitrogen temperature was,possible in all cases only from the p region-,t

the diodes wi_s_fi~iestigated in fact. A 16%'-wave Iradiation, whose intensity decrease

of the spectrum to zero energy yielded the value of the energy gap,,the narrowing of

TOPIC TAGS: vinyl compound, organic synthetic process, organotin compound
,ABSTRACT: in the reaction of triallcylalkoxystannanes with enolacetates of
_Lsobutyric and isovaleric aldehydes, probably as a result of steric hindrances,
I.previously undescribed organotin 0-derivatives of the enol forn. of the aldenydes
are formed instead of the expected alpha-stannylated carbonyl compounds.
;'Dropwise addition of trialkylirethoy-jstannane to the enolate of the corresponding"
I-aidehyde produced exothermic reactions, yielding vinyloxystannanes: triethyl-
(beta,be-ua-dinethyl)-vinylox-jstannane, triethyl(beta-isopropyl)vinylo>-.ystannane..,
and tripropyl(beta,beta-diinethyl)vinyloxystannane. The infrared, ultraviolet,
and proton magnetic resonance spectra of the compounds obtained are discussei

TEXT: Examples are quoted for distinguishing tectonic dislocations
of the fault-, step-, and graben-type from the seismic prospecting
data of the Kt~7~3 (KMPV). Theoretical hodographs of the main waves
were computed for different angles of the intersection of the ob-
servational Drofile and the line of tectonic disturbance. In addi-
tion, methods of determining the location of a fault from the pecu-
liarities of the wave picture are indicated. [Abstractor's note,.

Title : Determination of tfi7e-!!iueC~�--and Orientation of an Unfaced Crystal
from One Photograph of the Stationary Crystal in Polychromatic Radiation
Orig Pub : Kristallografiya, 1956, 1, No 2, 159-164
Abstract The determination of the Iaue class and of the orientation of an unfaced
crystal is usually performed by taking three photographs in a flat
cassette. This article proposes that this determination be performed
for crystals giving a rich interference pattern by using a single photo-
graph in a cylindrical cassette. The spherical coordinates of the re-
flexes and of the points of intersection of -uhe zonal curves are determined
with the aid of a grid of curves =const and P =-const. The data ob-
tained are plotted directly on a rcdccrov sphere, thereby simplifying the
work and reducing the time of determination.

ABSTRACT: Conversion spectra of the neutron-saturated dysprosi-x"n
iso topes were irive3tigated here. The dysprosium fraction
was chemically and chromatographically separated from the
tantal-am target bombarded with fast protons in the synchr3-
cyclotron OPIJ3,4 The irradiation lasted several hours, the
separation of the rare earths took place 20-70 hours after
the termination of the irradiation. The situation was mo--r-a
complicated than was to be assumed according to tha Sibor.-
tables. In the conversion spectrum the authors determined
lines whose intensity
y decreased with half life3 of-, a)
7,5 111 hours, b) 38 hours and 0) 4,7 days. Du~: tc th,~
difficult situation explanations are here given according
to groups of half-lifes. The Dy-fraction was in-trestigated

-fraction 15 electron-lines whose intensity decreased with
a half-life of 7,5 " 1.1 hours were determined in the range
0
of 3- 1 150 keV. All lines repeated themselves J.r 6 series
(perfo~rined with 2 sources). The value of the half-life of

-electrons, the lines with 1395, 57~5, 64iO, 74~O and 81.0
keV were identified as conversion electrons K, L and Y, of
the transitions with 65,5 and 82,5 keV in Tb. The electron

lines (with 10 hours) weaker lines of the conversion
electrons, the intensity of which decreased with a half
life of (4,5 + 0,2) days became distinctly visible, K-.
L- and M-elec7trons of the transitions with 63 and 87 keV,
L- and M-electrons of the transit-Lon with 57 keV, K- and

keV, K-electrons of the transitions with 60 and 262 keV
were determined, Some of these lines could not be identified,
.- It is shown that the activity decreasing vrith a period
of 4,5 days can be ascribed to the terbium, isotopes. It
seems that at least 4 terbium isotopes with a half-life
period of about 5 days exist;
155 (T = r,6 days), Tb157 'T
Tb153 (T V days), Tb j k
4~7 days) and Tb 161 (T = 6,8 days). Sumgiarizing thp
authors state that it is Possible that Tb has a
of about 5 days, that it is accumulated from DyI577 (T

TITLE: Conversion Elecl6ron Spectrum of" the Cerium Fraction (Spektr

PERIODICAL: Izvestiya Akademii nauk SSSRj Seriya fizicheskaya,
1958, Vol. 22, Nr 6, pp. 93*1 - 934 (USSR)
ABSTRACT: The activity of the cerium fraction in all sources obtained
by the authors by irradiation at different times was small.
At the beginning of the measurements the counting rate of
the most intensive conversion line was goo pulses per minute.
The spectrum of the conversion electrons is shown in figures
I and 2. Table 1 gives the energies of the lines, their
possible identification and their relative intensities. The
15 electron lines that are found are classified into 3 groups
according to their half-life. The inten-sities of the electron
lines with energies of 126,2 and 159;1 keV decreased very
slowly. These lines are apparently produced by the K- and
(L + M) conversion electrons of the well known -y-transition
Card 1/3 hv=165 keV of the Ce139 isotope (T 1/2 IiJO days). The

I

intensity of the electron lines 212v8 and 248 keV decreased
with a half-life of 3-4~ hours. These lines can be identified
as F.- and (L + M) conversion lines of' y transition. The
value of the ratio K/(L + M) indicate!3 a multifole type E3
(Table 2). An isomeric state with an energy of 256 keV
corresponding to IL ~aif-life of 34,5 '-tours (Ref 7) exists
in the isotope Ce'31. The authors are of opinion that con-
sidering the comparability of the decay energy (half-life
energy) and of the multipole order energy of the observed
transition with the data of the isomeric transition in
Ce137 the activi y with a half--life of 33 hours could be
ascribed to Ce13~. Thes,~ data do not contradict the decay
scheme suggested by Bro5i anC The intensity of the
remaining lines decreased with a narf-life of 17 hours. The
evidence obtained by the authors is not sufficient to ascribe
the lines with a T 1/2 of IT hours to o-ne definite Ce-isotope
or to one of its daughter products, or to set up decay schemes.
The authors express.their gratitude to zhe synchrocyclotion

ABSTRICT: The study was concerned with the low-energy part (up to 100 keV) of the
conversion electron spectrum of the Pd fraction separated chemically from a silver
target bombarded with 660-MeV protons on the synchrocyblotron of the Mal (Joint
Institute for Nuclear Research at Dubna). The Pd activity was deposited on a tan-
talum plate and then transferred by thermal evaporation under high vacuum onto a
lightly aluminized mica,sheet 2 mictons thick. The spectrum was recorded by means
of a magnetic lens P-spectrometer with intermediate acceleration. The measurements
were started two days after separation of the Pd fraction. The electrons were de-

TEXT: The energy of Auger electrons was measured with a magnetic-lens
beta-ray spectrometer of the Kafedra yadernoy spektroskopii LGU (Department
of Nuclear Spectroscopy of LGU). The electrons were accelerated with an
electric field on the section of the flight-path section parallel to the
axis of the apparatus between two lenses. The counter, filled with argon
and alcohol vapor (ratio 1:1, pressure 26 mm Hg), was sealed by a collodionVK
film with a transmission threshold of 3-4 kev. Electrons of more than
27 kev were completely transmitted. The apparatus was calibrated by the
A- and F-lines of ThB and the L 58-line of Dy 159. The relative half-width
of these lines was 2.0 %. Samples were obtained by chromatographic
separation of the rare earths from a tantalum target which was bombarded
