ABSTRACT: The authors describe-a coincidence dircuit.with a theoretical resolving'
time of 1.5-10-10 sec for usejn aAetector-for measuring,the total effective
cross section of interaction between neutrons and nuclei by the

The operating principle of the circuit is as-foll6ws: 'If-pulse's with a ste.ep
front are fed to the input of the shaperin the coincidence circuit, the trigger-,
ing moment of the device at any threshold depends on the-,heigbt of these pulseso
Even when the sensitivity of the circuit is high, the time scatter lies within the-T-.:
limits of the pulse front. Thus the resolving time of the circuit for 100% effi-
ciency has a direct relationship to the rise time of the pulse. This time scatter

Abstract Based on ordinary thermodynamics and statistics, an analysis D3 made of
theeffect of pressure on the properties of a solid body. Assuming the ion 2
interaction potential to be in the form U(r) = Z_exp X r)_7 (A + Br + Cr
t Dr-1), where r is the distance between ions and Y A,B,C;.and D are con-
stants, the author finds the maximign frequency of the elastic collisions of
the linear monatomic chain, comprelsed with a force f, and derives an equ~ation
for the dependence of the DeIrje temperature & on f. The equation contains an
exponential factor and consequently 61 should increase sharply at sufficiently
large f. The dependence of 6) on the pressure ~ is derived for a three di-
mensional crystal lattice with cubical symmetry.

TITLE: On the problem of anisotropy of the electric conductivity
in ferromagnetics. (K voprosu ob anizotropii elektro-

PERIODICAL: "Fizika Metallov i Metallovedeniyell (Physics of Metals
and M_et_a_1lu_r_9_77_,_1"5 , Vol-IV, No-3, PP-385-391 (U.S.S.R.)
ABSTRACT: The problem of anisotropy of the electric conductivity
was considered by several authors (2-4). Baroody, E.M.0)
determined the anisotropy of the electric conductivity by
solving the kinetic equation. He investigated two cases,
namely, when the function-characterising the inter-relation
of the electrons with the lattice oscillations is isotro *c
and the energy depends on the wave vector (and not on I jk)
and when the energy is isotropic and the anisotropy is
taken into consideration as a function of the inter-relation
of the electrons with the lattice oscillations. The work
of these authors related to non-ferromagnetic metals and
were based on the single electron approximation. Akulov,N.S.
(6) has shoz-n that the anisotropy of electric conductivity
in ferromagnetics can be determined phenomenologically from
Card 2/4 the symmetry properties of the crystal alone. On the basis
of the quantum mechanical model of the ferromagnetic,

126-3-1/34

Vonsovskiy, S. V. and RodionQv, K. F.(?) calculated sezi-
phenomenologically the anisotropy of the electric conductivity
approximating the free electrons in a metal by means of the
Drude formula. Of considerably greater interest is accurate
calculation based on taking into consideration the micro-
scopic anisotropy in the kinetic equation. The aim of this
paper is to determine the anisotropy of the electric
conductivity of the ferromagnetic metal by solving the
kinetic equation,using the concrete type of energy spectrum
of the conductivity electrons determined in the dissertation
of Turov, Ye. A. (Sverdlovsk, 1954). It can be seen from
the derived relations that,in aSTeement with experimental
results,the change in the electric conductivity,after taking
into consideration the spin-spin interaction of the s- and
d-electrons in the longitudinal and transverse cases, is
proportional to the square of the magnetisation of the ferro-
magnetic (Thomson-Goldhammer effect). The (s-d) exchange
model used by the authors does not take into consideration
all the features of ferromagnetics. However, the effected
calou"ations indicate that,within the framework Of this
Card2/4 model,deviations from the law of the even effects of Akulov
are obtained if the microscopic anisotropy is takeninto

consideration in the kinetic equation. The magnitudes
a and a' eq,(19), to which these deviations are due,
2 2 t
include the isotropic as well as the anisotropic part.
Eqs. (20 and 21), P.390, express the resulting relative
changes in the electric conductivity as a function of the
direction of measurement and it can be seen that the Signs
of the longitudinal and transverse effects coincide, which
is in agreement with experimental data. Bates, L.F. (10)
has established that there is an anomaly in the relation
between the signs of the longitudinal and the transverse
effects in the case of high coercive alloys, whilst
Drozhzhina, V.I. and Shur Ya. S. (11) have established
the existence of such anomaly for high coercive as well as
magnetically soft materials; the signs of the effects were
equal. On the basis of general symmetry considerations,
Vonsovskiy, S. V. (12) explained this anomaly by the
presence of "volume" effects and he established a criterion
governing equality of signs of the two effects, pointing
out that the microscopic theory should explain, at least in
Card 3/4 principle, the possibility of existence of this criterion.
The eqs.(20 and 21) derived in this paper indicate that this

criterion is fulfilled in the given case. Acknowledgments

ABSTRACTI: An apperatus dependent on observations on bendinC (not
de&--ribed in 4etail) is used at hydrostatic pressures up
to 5000 k./cmI. Electrolytic copper and aluminiuarli,
99."5-019.95% pure, and medium-carbon steel are used; the
re-Sults ~~re given in Table 1 (left column: Al, Cu, Steel;
units c~ /kg; columns: frog (2), from experiment), for
pressures up to 4000 kg/cm . These metals were used
beca,usa buhe bulk (K) and shear (G) moduli are known for
hin.-?_ hydrostatic pressures. Eq.(2) is derived by
differentiating the standard Eq.(l); Eq.(3) is an
approx~iate formula relating K to p due to Bridgnan.

paper gives a theoretical analysis of behaviour of
thermal conductivity of a crystal subjected to
uniform pressure. The analysis assumes the existence
of a free mean path length for a phonon in the crystal
lattice of an insulator. The author derives two
expressions for the thermal conductivity of an
insulator at high (Eq.?) and Tory high (Eq.8) pressures.
It is not possible to give a quantitative estimate of
thermal conductivity using Ea.? or 8, because for the
majority of insulating crystals there are no reliable
theoretical or experimental data on the variation of
thermal 'expansion and heat capacity with pressure,
which appear in these equations. For NaCl, NaBr,

also a qualitative prediction that thermal conductivity

ABSTRACT: The author shows that compressibility and bulk modulus
of a solid can be defined in three different ways. These
are given below:
1. Compressibility is usually defined by the following
equation: 1 ~ 3V

The usual definition of bulk modulus is as follows:

The differences between the definitions can also be seen
when each of the quantities in Eqs (1) - (6a) is
redefined by substituting into these equations Bridgman's
empirical expression (Ref 2):

where A and B are constants. A is of the cLrder of

The results of such substitutions are given in Eqs (0413a).
The author shows that the best representation of properties
of a solid under high pressure is given in terms of the
intrinsic or "instantaneous" values of compressibility
and bulk modulus (Eqs 2, 2a, 5, 5a or Eqs 9, 9a, 12 and 12a).
The author uses Eqs (8), (8a), (9) and (9a) to calculate
changes in the bulk-elastic part of the lattice energy
and changes in the Debye temperature (Figure 1) with
increase of pressure. There are 1 figure and ? references,
4 of which are Soviet and 3 English.

istics of such solids must be estimated with the aid of the
classical models put forward by Debye (Ref.1), GrUneisen (Ref.2)
and Lindemann (Ref.3). It is well known that the characteristic
frequency V of oscillations in a crystal lattice ond hence the
Debye temperature also, increases with pressure. V For an iso-
tropic body the Debye temperature is given by

on the elastic moduli so that if the latter are known as functions
of pressure, then the Debye temperature given by Eq.(l) can be
estimated. Other physical characteristics such as speci ic heath'
melting point, thermal expansion coefficient etc. can then be
expressed in terms of the Debye temperature. This approach is used
in the present paper to calculate the Debye temperature as a
function of pressure for alum:Lnj-um,-L-lsllvervlcopper~~nd iron'land the

melting point as a function of press for ~- and aluminium. The
results obtained are shown in Figs. 1 And 2. In Fig.2 the
continuous line represents the experimental results obtained by
Strong (Ref.11) and Butuzov (Ref.12) and the dotted line shows the
theoretical results obtained by the present authors. The agreement
is good and hence it is concluded that the classical modelsemployed
lead to correct estimates for the parameters of a solid body as
functions of pressure. Acknowledgments are made to R.G.Arkhipov

or kerosene/tratisformer oil (graphs 2, 20) mixtures were used.
~Since the experiments described above were conducted for a constant
'degree of deformation, the next series.of experiments consisted in
extruding the alloys studied in the 75/25 mixture of kerosene and

deformation. The results confirm the previously established fact
that the relationship between P and Sf = In F/fo (where F and

extruded rod, respectively) is linear. The results of the next
