ABBITMACT: The authors propose a method,of using limiting conditions of a third
kind, more general than previously employed, in solving a differential Fourier
equation as a means of determining thermal properties. The technique for deter-
mining measured values,requires no observation of special conditions in setting up
the tests ' except the maintenance of uniformly symmetrical heating (and cooling) of
samples in an environment of constant temperature. Cylinders of magnesite, fire
clay, and foamy fireclay were used in the.experinnnts, and measurements were made
by reeans of Chromel-Alumel thermocouples with thermoelectrodes 0.2 mm in diameter,
connen.ted to an EPP-09 electronic potenticAneter. Errors in measured temperatures
did not exceed 2%. The method is simple and needs no special heating device. It
can be used in any plant laboratory and permits determination of tbnrmal properties

TEXTa Experimental results are available on the sheet by
sheet nonuniformities of the magnetic properties of hot rolled
dynamo and transformer sheet. However, such data are not available
on cold rolled sheet. This paper contAins some data on the variation
of these properties in cold rolled 0.35 mill thick and 0.50 mm thick
transformer sheeis. The data were obtaLned by means of Epstein
apparatus. For detailed study of the nonuniformity of the
induction of cold rolled transformer steel, sheets 1500 x 240 x
Oo35 mm were investigated by means of simple apparatus, the basic
circuit of which is shown in Fig.l. It consists of plywood frames:-
placed on top of each other, 1400 mm long with windows of
20 x. 260 mm. A metering coil of 600 turns is mounted on the
central part (3/5ths of the length) of each frame. The magnetiza-
tion winding surrounds both frames and has 522 turns, which are

The resulting longitudinal distribution of the induction in a pair

The indicating instrument is a magnetoelectric one, which is series
connected with a half-wave controlled bridge rectifier made up of
equal cuprous-oxide elements. The instrument is shunted with a
smoothing condenser and with a resistance for the purpose of
adjusting the sensitivity. The indicator coils are connected in a
differential circuits The control voltage is obtained from a
supplementary win ding with 80 turns, which are wound on a central

value of the e.m.f. difference in the metering windings, as a
result of which the rectifier circuit is piactically blocked for a
half-cycle of the control voltage, whilst during the other half-
cycle it shows only a low resistance to the current flow in the
:metering coils, regardless of the direction of the current (this

Thus, it was found that the nonuniformity within individual batches
of cold rolled transformer sheet is very considerable and, therefore,..
the properties of standard specimens chosen arbitrarily may deviate
considerably from the average properties of the batch. A real
increase in the testing accuracy can be achieved only by increasing

It is recommended that this can be done by means of the instrument
described in this paper-, using as a criterion the induction Blpy or
B2~ since the quantity of sheets scrapped due to unsatisfhcto

induction. It would be advisable to combine the system of
preliminary sorting of sheets on the basis of induction with
subsequent more accurate evaluation of each batch by means of
apparatus which permits obtaining absolute values. The work

_a~ali~n'of cold-rolled transformer
TEXT: The effect of final anne i
steel in vacuum on magnetic induction in weak and medium fields is not
sufficiently clear. Many steels with high induction capacity in strong
fields display relatively low induction in weak and medium fields. In
order to investigate this problem, tests were carried out with three
kinds of steelsz 6260 (SiO-16%), 6247 (Si:3.23%) and 6230 (SiO-10%)-
Until a 0-35 mm thickness of the sheet was obtained the technological
process took place according to the conventional methods. Final anneal-
ing was carried out in vacuum electric furnaces up oto 1,1500C for 30
hours. The.metal was cooled by the furnace to 600 C, after removing the
hood cooling was continued to 2500C under a muffle in a protecting gas
medium. Test specimens (0.35 x 30 x 250 mm; 1 kg) were made of all
three types of steel, the magnetic properties were determined by the

Epshteyn ballistic method before and after the additional annealing which
was the main feature of the new process. Type 6260 was cooled by the
furnace between 6000C and 4500C to.various degrees and the types 6247
and 6230 were tested in 6 charges, three of which were cooled by the furnace
to 6000C and three to 4500C- The results obtained with the 6260 type
specimens showed that in proportion to the decrease of the temperature,
at which the hood is removed, the magnetic properties in weak and medium
fields improve; magnetic induction B 0 M increases from 1.25 to 1.62
gauss, B0.008 from 10.11 to 25.10 gau;s Fig. 1A) and B Ifrom 12,680 to
14,650 gauss; the coercive force H increases from 0.18 to 0.13 oersted,
maximum magnetic permeability/.z., from 18,280 to 36,380 gs/oersted
max
Fig. 2),q the plasticity of the metal increases from 2.7 to 18 bendings.
This change in the magnetic and plastic properties can be explained by
a more thorough distribution of the internal stresses upon the removal
of the hood at a lower temperature with a corresponding re-distribution
of the admixtiires (Ref. ~). With additional annealing of the specimens
at 7500C, in order to eliminate work hardening due to cutting, the

improvement of magnetic properties can be maintained. The results obtained
with specimens of 6247 and 6230 type steels agree with the results of the
6260 type specimens. Generally, it was found that after the additional
annealing of specimens to eliminate the work hardening due to cutting,
the yield of products complying with F'OCT (GOST) 802-58 increased from
40% (in the conventional cooling by furnace to 6000C) to 80%, when cooling
with the furnace to 4500C. There are 2 figures, 2 tables and 2 Soviet

The maximum field strength is about 15 oersteds. 'Thus it is

the individual cold-rolled batches. It was also apparent that
tests by the Epstein square give only very approximate indications
of the properties of the batch. Even in scrapped batches, the
number of sheets that eventually proved satisfactory was over 50%.
It is necessary to increase very appreciably the number of sheets
tested. However, it in sufficient to limit a test to measuring a

The Problem of theThgoing Cross Section of Holes in
Germahium by Defects Formed by Gamma Irradiation Ig
Fizika tverdogo tela, 19609 Vol. 2, No- 4, PP. 566-56a
TEXT: The trapping cross section of holes by defects formed by neutron
bombardment vas found to be - lo-15 cm2 (Refs. 1-3). The trapping cross
section for gamma irradi&tion was 4 .10-16om2. The present paper shows
that this difference is due to a false assumption: A defect formed by
gamma irradiation has not two but four acceptor levels in the forbidden
band. The dependence of the lifetime on the irradiation with gamma
quanta was determined on 11 specimens, wherefrom the trapping cross
section of the holes was calculated (Table). A Cobo preparation with an
activity of 400 gram-equivalent Ra was used as gamma source. The authors
used the photomagnetic method, the method of photodiffusion, and the
examination of the relaxation curves of photoconductivity to measure the
lifetime. The mean value of the trapping cross section was found to be
3.8-10- 15cm 2. This is close to the value obtained for the neutron

defects, the authors made a number of experiments which are described
here and whose results are discussed in detail. The main purpose of the
experiments was to determine the effect of 7-induced defects on the

The sample is placed in a cryostat between the poles of an electromagnet
which can generate a field of up to 4,000 oersteds. This cryostat permits
a change in temperature from room temperature to that of liquid nitrogen.

TITLE: Investigation of the kinetics of impurity photoconductivity
for the purpose of determining the parameters of local
levels
PERIODICAL: Fizika tverdogo tela, V. 3, no. 1, 1961, 252-266
TEXT: An investigation of impurity photoconductivity is not only of
interest in principle, but is also of practical importance for studying
the local electron states in the forbidden band and especially of its
interaction with exciting radiation. Apart from an earlier paper by the
authorst relaxation processes of impurity photoconductivity have hithert
not been investigated in detail; this was, however, the aim of the present
voluminous paper. The authors set themselves the task of investigating
theoretically the most important cases of photocurrent relaxation during
excitation in the impurity region. The rules governing the kinetics of
impurity photoconductivity have certain peculiar features as is shown

here, due to which impurity photoconductivity relaxation differs
essentially from that of intrinsic photoconductivity. An exact analysis
of these rules shows that an experimental investigation of the kinetics
of impurity photoconductivity may serve the purpose of determining
various parameters of impurity centers as, e.g., the photon capture cross
section, the trapping cross section for free carriers, as well as the
energy position of the impurity level in the forbidden band, the
concentration of centers and the degree of their completion. In part 1
of this paper, the most important rules of the kinetics of impurity
photoconductivity in the excitation of carriers for one type of local
centers are dealt with. This is done on the basis of an example of a
semiconductor, in whose forbidden band there is a sort of local level
with concentration M; these levels are assumed to be in the upper half of
the band, so that they are in heat exchange with the conduction band.
This semiconductor is irradiated with monochromatic light of such a
wavelength that only electrons pass from the local levels onto the
conduction band, and that monopolar impurity photoconductivity occurs.

Low-temperature breakdown in germanium in connection with
TITLEt
radiative defects
PERIODICAL: Fizika tverdogo tela, v. 3, no. 4, 1961, 1298-1300
TEM In germanium doped with elements of the third or fifth group, the
current may suddenly rise at helium temperatures when the field applied
exceeds a certain critical value. This effect is known as low-temperature
breakdown. The following is the mechanism of this effect; At these tempera-
turesp the majority of carriers causing impurity conduction is localized at
impurity centers, and resistivity is high. When a field is appliedf the free
carriers are accelerated and, at a certain field strength, their energy is
high enough to cause impact ionization of the filled impurity centers, The
low-temperature breakdown in Ge or Si due to donor or acceptor impurities
has been investigated repeatedly. The present paper is a report on studies
of this effect which is caused by radiative defects; such defects have been

First, the energy levels of the radiative defects are discussed; Fig. 1
shows the level scheme for gamma-irradiated (a) and faat-neatron irradDateft
(b) germanium. The two shallow levels of the radiative defects axe only
0.02 and 0.01 ev, respectively, off the valency bandl at helium temporatur,r"',
they are occupied by electrons only partly or not at all. In neutron-iv-
radiated Go specimens, the 0.01-ev level was found to be free from clectrcais
at helium temperatures. In chemically impure specimens, the presence of
donor centers offered a certain compensation, and the level wa8 partly oc-
oupied by electrons. Volt-ampere characteristics of such specimens were
taken by means of a "characteriograph.11 They were analogous to those ob-
tained by B. Vul, E. Zavaritskayal and V. Chuyenkov for the low-temperature
breakdown due to impurity centers. Altogether; three specimens were examin-
ed; gamma-irradiated 1-,r had a concentration of shallow radiation levels of
Na - 7-jol3cm-3 and a hole concentration on them of p a = i.iol3cm-3; 1-n and
2-n were n-type specimens having a resistivity of 2 ohm-cm; after neutron
irradiation they were p-type. n-type and p-type specimens having a resistiv-

TITLEs Impurity photoconductivity with gamma-irradiated germanium
PERIODICILi Fizika tverdogo tela, V. 3, no. 10, 1961, 3211 - 3219
TEXTs gamma irradiation of n-type germanium gives rise to an appreciable
impurity photoconductivity which exceeds that in nonirradiated germanium
by some orders of magnitude. 'It was examined in n-type germanium
specimens (Q - 20 - 30 ohm-cm irradiated with Co 80 quanta. Since
irradiation took place at .INC, the radiation defel were stable at
room temperature. The experimental setup is shown in Fig. 1. The
specimen was placed in a cryostat with Or- indow. All measurements wero
made at N1000K. Parasitic light was eliminated by a set of filters. The
gamma-induced defects in n-type Ge form four levels in the forbidden band
which are 0.02, 0.11 and 0.*26-ev above the edge of the valence band and
0.2 ey below the bottom of the conduction band. The Fermi level was con-
siderably above the level at 0.2 ev throughout the temperature range in-
volved. The typical dependence of this photoconductivity on the energy

of incident quanta is presented in Fig. 3. The relaxation of unipolar
impurity photoconductivity was also examined. In these experiments, the
light frequency was chosen such that electron transitions occurred only
from the 0.2-ey level. Growth and decay curves of photoconductivity, when,
respectively, switching the light on and off, are "asymmetric" and do not
obey the exponential law. The experimental results may be explained by
calculations of S. M. Ryvkin et al. (FTT9 III, no. 1, 1961). quenching
was obseryed in all n-type specimens when irradiating simultaneously by
light corresponding to the self-absorption band and the impurity band.
Fig. 5 presents typical curves of quenching spectra. The complicated
characterl the great variety of relaxation curves, and of spectral proper-
ties of querohing are due to the superposition of two concurring processes,
namely, of quenching and of the impurity photoelectric effect. The shape
of the spectral distribution curve, while depending on the ratio between
the two light intensities depends on the experimental conditions and is
not characteristic of the examined material. Conclusionst The radiation
defeats forming as a result of gamma irradiation of germanium gives rise
to an impurity photoconductivity reaching as far as 6 microns. The posi-
tion of the two independent radiation defeat levels agrees with results

Yaroshetakiy, FTT v. 3, 211, 1961), using a larger y-ray flux in
order to observe a more extensive line spectrum in the forbidden band

enclosure. The spectral curves disclose a large number of bends and
ledges, pointing to a complicated spectrum of the local levels in
the forbidden band. Measurements of all the investigated samples
indicate the presence of the following energy levels: Ev + 0.52,
Ev + 0.48, EV + 0.43, Ev + 0.41, Ev + 0.37, E V + 0.33, Ev + 0.31,
and Ev + 0.27. This spectrum coincides fully with the spectrum of
the local levels produced in the central part of the forbidden band
when germanium is irradiated with fast neutrons, to which the levels
with, energies Ev + 0.31 and Ev + 0.43 eV, which are symmetrical re-
lative to the center of the forbidden band, are added. It is fur-
ther concluded that the various levels introduced by impur-
ities in the central part of the forbidden band are not due to any
clustering of the point defects with the atoms of the doping impur-

is suggested that they may be the results of the decomposition of the polymers under

may be caused either by differences in the centers themselves, or by differences in

ABSTRACT: This is a continuation of earlier work (ZhETF v. 50, 2735, 1966), and con-1
tains more detailed information on the fatigue produced during optical destruction
of transparent bodies in polymers (polymetbylmethaerylate and polystyrene). Tibe ex-
perimental procedure was the same as in the earlier investigation. 71he radiation
source was a neodymium laser operating in the ordinary-pulse mode. The tests con-
sisted.of determining the influence of energy on the number of irradiations necessary!
for the first visible crack in the material to appear, or the change in the dimensioW
of the damaged region with changing number of pulses. Comparison of the results of
the two tests has shown that the true threshold of optical strength is approximately
one-third as high as expected from an analysis of results of damage produced by
single irradiation. An investigation was made of the nature of the irreversible
changes due to the fatigue occurring at pulse energies lower than critical (necess

of complete softening, and the increase in the visible cracks upon repeated irradia-
tion. It is thus concluded that fatigue effects must be taken into account in stu-
dies of damage to transparent materials by laser beams. The authors thank I. A.-

ABSTRACT: This is a continuation of earlier work (ZhETF v. 50, 1187, 1966 and else-
where), where it was shown that a laser beam produces cracks in alkall-halide crys-
tals. although no detailed description was giVen of the nature of the cracks). To de-
termine this structure and to explain the mechanism whereby the damage is initiated,
the authors investigated LiF single crystals measuring 20 x 20 x 20 mm cleaved alon.-
the cleavage planes. A neodymium laser operating in the spiked modewas used. The
beam focusing procedure iias the same as in the earlier work, the damage was - exarained
under'a microscope, and the dlslo~ation slWucturawas revealed by selective etching.
Besides confirming the earlier results,, the present tests - demonstrated that the
damage produced by the laser pulse consist; of a main crack in the cleavage plane

the damage) either in air or in the oven, led to'healing of the cracks characterized
by a unique structure of the front of the annealed rosette. "lile the causes of this
