TITLE: Spine generators and the prospects of their

TEXT: The possibilities of applying spinet generators for
directly measuring the: magnetic field are discussed. The follow-
ing types of isuch generators are considered. (1) The Schmelzer
generator in which a Ejyjtem of magnetic moments having the natural
frequency wo = -f Ho., where Y is the magnetomechanical ratio
and H 0 is the intensity of the outer field., is used as an equi-
valent oscillatory circuit. When appraising the possibility of
the practical application of this generator, the author considers

Spine generators and..., D228/D305
that the best results oan be obtained by using in it an electron
magnetic resonance in a sodium-ammonia solution* (2) A generator
with a flowing pattern in which the precession of the magnetiza-
bility vector in the field under measurement 15 sustained by a
continuous influx of liquid with an unequiponderant degree of
magnetization: The essential defect of this generator is its
cumbersome nature connected with the system of tubes, pumps, 9te,
(3) "Ma8er"-type genexators, i.eo, quantum systems which, on the
absorption of a definite magnitude of a given frequency, emit
great power of the same or leseer frequency: Such generators
include the "maser" with a flowing pattern and the "maser" uti-
lizing the inverse effect of Overhauser. A general defect of all
the above-mentioned generators is the presence in them of adjusted
circuits which under ce--tain conditions may lead to the appearance
of the coupling-hysteresis effect and consequently to negligible
deviations of -the frequency of the generated oscillations from
the Larmor frequency. "Masers" based on the principle of optical
"pumping" in couples of alkali metals are of considerable interest

ABSTRACT: The width of the resonance line in a helium amignetometer was measured
during a pulsed discharge in the absorbing cell. The metisurements were conducted by
rieducing the rf field amplitude to a level at which the vidth of the observed signal
was practically independent of the saturation factor. A further reduction in the
line width requires a decreased optical width, which is obtained by lowering the in-
tensity ol! the light source. However, in t"-case the signal strength is also af-
fected. Xt was found that during a.pulsed excitation, the width of the magnetic resi
nance line can be reduced ito 1.2 x 10-5 oe,i.e., almost 50 times narrower than the
line width obtained witha continuous discharge. With rf broadening taken into accou
a line width of the order of 3 x 10-5 oe can be obtained. Thus, the use of a pulsed
discharge.eliminates the basic deficiency of the helium magnetemeter, i.e., the larl
width of the magnetic resoaance line. In comparison withrubidium and cesium magneW

ABSTRACT: This pape.-Ae & continuation of invea-L"'Lgations of the,spe-

(Arai ' der 1hyse vo 1.4. 2:29'~ 1964 and v. 15.. 5., 1!)65). The correctness
of ';~e met,,od employed In the article was also Investigated previously
(Ann. der i~ys* v. 1% :L83~ :L965). Basic equations are first derived.,
describing -the motion of a composite particle in an external field, and
ii; is shown that the ratio'of the coefficients of barrier penetrability
in opposite directions must depend on the shape of the barrier. The

'cc NRI AP5026601
energy dependence of the effect under discussion at the threshold of
excitation of the composite particle is given,, after the effect is
analyzed for the limit'ing case of small barrier asytzwtry. The results
of computer calculations -ror a specific potentizil barrier are then
presented. It is shown t'hat the penetration coi)fficients for asymmetric
barriers in opposite direotions may be very difTererat for composite
particles if their energy,io.sufficient for actual excitation of the
higher states of internal moltlion. This effect ohould manifest itself
in variolas atomic and nuolear phenomena. Authors thank S. N, Sokolov,

of the turbulent mot-~on in the critical region promotes
the eavlier obtainipg of a temperature equilibrium. It can
be maintained that a complete therao-dynatio equilibrium
was obtainad, that in Tj (pjT) - 92 (p#T)
so that the experiment may be carried out without any
mixture. Illustration I shows the transformation of the

by approximation towards the critical point (that is with
incra.aing specific volumes)p although the absolute value
of these flexions continues increasing in the heterogene-
ous domain. Transition is extended over a considerable
temperature section (up to 4.50 in the case of water).
It was found that the critical region for water with regard

the values of Krillin and Zubarev. From the classical point
of view the increase of the a. of water in the 2-phase oondi-
tion at transition into the 1-phase condition can be explained
by the fact that an added quantity of heat is not only con-
umed for the temperature increase of single phases but also
;
or the separation of molecular bonds of a oompoun46f many
molecules. Vaporization heat cannot have an essential influence
on the transformation of the ov as with its approximation
towards the critical point its value tends towards zero.
In the meantimo the extent of the Gr-flexion increases. At
the point of transition into the 1-phase condition dieso-
oiation process and vaporization suddenly cease. This causes
a jerky decrease of cv. At the critical point the number
of separated molecular bonds reaches its maximum, which
causes a maximum increase of the o.-value. By means of
the equation of Van-der-Waala the above described behavior
of the subtanoe at other than critical temperatures

tablets by cold pressing under a pressure of 40oo kg/cID2 and by
6 hours hot pressing at a. temperature of 4000C under a pressure
of 36o kg/CM2. The thermal conductivity was measured by the
compensation method with the use of a vacuum for avoiding the oxi-
dation of the sample. Special investigations of the course of
temperature of the heat capacity werb additionally made by an
adiabatic microcalorimeter. The existence of charge carriers of

ABSTRACT: Though most of the wark3 deal with the determination of the
age of eruptive rookeand minerals, tho prinary conditions
of radioactive geochronometry can also be eil;plied with
depocitions. That requires that a precipiteling mJ-ieral
contains a radioactive mother-rock, and furiber that the
developing daugther-i-ock remains well oonse:tved in the
mineral and thiLt it is not containiid in the mineral in the
moment of precipitation. Finally it is required that the
moment of form;xtion of the respective miner.0 agrees with the
moment of precipitation of all other fiediments of the
respective hor:Lzon containing it. Since the tboolute age
of the sylvinite cov.Ld be determined (refoxonce 1), this
problem was attacked with respect to an au-thigenic mineral -

MIODICW. Doklady AN SSSIts 1958s Vol- 118, Nr 2. pp. 328-330 (USSR).
ABSTRACT: Glauconite was chosen for the determin;ktion of the absolute age of
sedimentary rocks due to its great structural similarity with mica,
especially with biotite* The first samples showed good results., as
far as the agreement of the absolute age with the assumed geological
Uge t3 aowerned. 9eside data on a gocd stability of the glauconite
atructure a weak potassium-linkaea to the lattice (reference 4) is
indicated. The preservation of potassium and thus also of radiogenic
argon appexently depends on the state of dispersion of the micas* In
glauconitos from Dagestan sometimes vary small contents to complete
absenev or radiogenic argon were determined. The method was described
in ear2iier papers (references 7-9), la order to determine the problem
mentioned in the title, the dependence of the separated radiogenie
argon on the temperature of heating vas irvestigated. Simultaneously
samples for an X-ray structural analysis were produced. The remainint

ven in ta!Dle and figure L About, 2oo/o of radiogenic argon are already
lost from glauconite at 1000C. At 5oooc argon is entirely separated.
Argon is., for instance, much more solid],y bound to muscovite and mist
crocline. Itis linkage to the crystal lattice of glauconite, howevers
is veryreak. As separation of argon alx9ady takes place before the
destruction of the glaueonite lattice, as the X-ray structural analya
s:L9 (table 2) proves. When comparing the curves of the separation of
radiogenic argon with those of the thermal analysis (reference 12j,13)
it will be seen that the 2 endothermic effects (between loo and 2oo0c,
and between 5oo and 6ooOC, respectively) of the latter (separation of
the adsorbed, water and loss of the watcr of constitution) are in agree
meat with the peaks of the curve of the separation of ar&on, The loss
d--~of the adsorbed water apparently, entails the loss of 2oO/o argon,
whereas that of the water of constitution causes the separation of
the argon residue. This also indicates a weak argon- and possib3,v alm
so a weak potassium-linkage to the glauconite-lattice. iurther inven
atigatitins are necessary. For determining the absolute age of the
sediments aocording to ~lauconitea a sufficient knowledge of the geow

On the Diffusion of Radiogenic Argon in Sylvites
Geokhimiyaj 19599 Nr 6$ PP 538 - 545 (USSR)
The- diffusion constants of radiogenio argon, the activation
energy of diffusion, the electrical conductivity of frequencies
of 0 - 20 megacycles and their activation energy were measured
on two different types of sylvite - red and pink - of the Soli-
kamsk deposit in the temperature range of from 20 to 7000C. The
diffusion mechanism of radiogenic argon was found to differ from
the conduotivity mechanism and the eigendiffusion of K The
activation energy of diffusion is at equal temperature higher
than the activation energy of conductivity Activation energy is
not likely to decrease at low temperature iunder 2000C). It is
not possible to make spatial diffusion responsible for argon
losses occurring in the couree of geological evolution. The dif-
fusion constant amounts to 10-300M 2/aeo extrapolated to a temper-
ature of 300 DK. Diffusion according to pair vacancies and
Schottky-defects is assumed to be the most probable diffusion
mechanism. Lrgon losses by desorption at low temperature on one

TITLE: The Anisotropy of Thermal Conductivity in a Single Crystal of
Tellurium (Anizotropiya teploprovadnosti v monokristalle tellura)
PERIODICAL: Doklady Akademii nauk SSSR, 1959, Val 124, Nr 3, Pp 554-556
(USSR)
ABSTRACT: The present paper gives the results obtained by measurements
of the thermal conductivity on a tel`.urium single crystal bred
in a furnace by sluw cooling from 7'5')'-' K to room temperature.
The tellurium casting thus produced (length 6 cm, diameter
2 cm) wan a massive single crystal without any fine-crystalline
inclusions. The single crystal was split along its parallel
surfaces and formed reflecting faces at the points of fracture.
From this single crystal samples were out out parallel and
vertical to the cleavage face for the purpose of measuring
thermal conductivity. Also electric conductivity and the Hall
effect were measured. The method of, measuring thermal conduc-
tivity has already been described ix one of the authors' pre-
vious papers (Ref 1). A diagram shows the temperature dependence
Card 1/3 of thermal conductivity and a at?nond diagram shows the

The' Anisotropy of Thermal Conductivity in a Single SOV/20-124-3-16/67

dependence of the electric conductivity of the samples within
the temperature interval of from 1D0 to 6400 K. The curves of
the first diagram-show marked anisol;rcipy of thermal conductivity
in the direction of the crystallographio axes of the single
crystal, which becomes weaker with Lnereasing temperature..
Numerical data concerning this anisotropy are given. The
anisotropy of thermal conductivity in a tellurium single
crystal is probably connected with the fact that in a heat
flow alo:nC the cleft, thermal resistance is essentially due
to phonon-phonon scattering. However, in the case of a heat
flow that is vertical to the cleavag
ge plane, there is,
besides phona-~-phonon scattering, also a considerable amount of
scatterimir, of phonons on the crystal layers, which act as
additional scattering centers. At low temperatures of about
up to room temperature, that part of -thermal conductivity
which is due to electrons may be neglected as being infinitely
small, and the total thermal conductivity in this temperature
interval may essentially be ascribed to the thermal diffusion
of phonons. Next, expressions are E:iven (separately for low
Card 2/3 and high temperatures) for the dependence of the thermal

conductivity coefficient of a tellurium single cryatkl
paralletl and vertical to the crystallographic axes. The
lesser degree of decrease of thermal conductivity in a tel.Luri-
um single crystal at high temperaturen can, as in the ease of
polyorystalline sairplea$ be ascribed to the participation of
current carriers in the transfer of thermal enerf-j,, Various
indications tend to show a diffucion and recombination of
electron-hole pairs. There are 3 filuren and 3 Soviet referen-
ces.

TIT LE: The Diffusion of Radiogenic Argon in Feldspars (Diffuziya
radiog-snixogo argona v polevykh shpiktakh)
PERIODICALi Daklady jkkademii nauk SSSR, 1959, *Vol 125, Nr 6, PP 1345-1347
(USSR)
ABSTRACTs It is known that considerable los.-as of radiogenic argon A40
4
formed. in feldspars by the radioactive transformation of K
occur in the last mentioned mineral. The linear approximations
in tho references 1,2 distort the separation mechanism of A40.
The authors give in this paper investigation results of the
separation kinetics of A40 in two Precambrian feldspar samples
(Ref *$). The figures 1 and 2 give the results. The diffusion
equation for a spherical case (1) as vell as the known depend-
ence Df the steady diffusion on the temperature (2) are used
for the interpretation of the obtained curves. Figure 1
(samgle IIr 1) shows that the heating curves have at 600 and
1100 horizortal sections of considerable length contrary to
Card 1/4 the depnndenoe (1). The slope of the curve increases against

the dependence 2 periodically, in intervals which are separated
from one another by curves with a horizontal section, not
gradually, with the temperature. A part of the sample Nr I was
pulverized in an agate mortar in order to clarify the nature of
these horizontal sections. Portions of 1.5 9 each were subjected
to differently long heating. The determination results of the
A40 which remained in these portions are indicated in figure 1
by crasses. The horizontal section is not shifted on the
vertical line, but only prolongated in the direction of the
ordinate axis. Thus its existence is caused by the structural
peculiarities, not by the grain size. The 2beginning of the
section is determined by the quantity D t /roin line with the
equation (1). The process occurring at 800 and 11000 can be
interpreted as rapidly dying down diffusion which exhausts the
A40_ con',ent in a certain stage. This stage is characterized by
valuee i;f E and D0 typical of it. Therefore the curves have t~
be interpreted according to A 40 which belongs to each single
phase. Thus the sample Nr 1 has .hreu phases (Fig 3: 1 and II
Card 2/4 the numbers of the phases). Fi6RITO 4 shows an analogous sub-

division of the sample Nr 2. The slope of the curves in the
figures 3 and 4 increases gradually for each phase with the
increase of t. This makes their analysis in the termn of the
equations (1) and (2) possible which confirms the rightness of
the authcors, interpretation. A ranter was contracted from the
equation (1) for different D-valuen in order to determine the
val-ae of D The D t-values were detected by applying this
raster tO Ee curves of the fi reii 3 and 4. 2 adjacent
Dt-valuev from the equation (2rwe;re determined. The obtained
Dt- and H-values as well as the D 273 -values, extrapolated
according to the equation (2), were compiled in the table 1.
This shoirs that each single phase is characterized only by the
E-value typical of it. The separation of A40 is carried oat at
the. m.lntioned temperatures by diffusion. The diffu ion4 8an,
however )ractically not influence the maintenance :f A as it
Is showi y the D .73-values for each phase. All losses of A40
in the voArse of the geological time are due to the separation
from the "zero"-phase only. The variety of the feldspars is
Card 3/4 not exhausted by the two samples, though the figure and the

ABSTRACT: The A- and He-separatian from one and the same sample was

of isoto-pic dilution 'Ref 1) which was somewhat modified for
this purpose. The measuring rosulto are given in figures 1-3.
The diffusion coefficients D and in several cases the activation

Pigure 1 shows curves for the carbonaceous schist, figure 2
for hornblende from granite-pegmatite, figure 3 for pyroxene.
Equal D-values of argon and helium for hornblende and
pyroxene prove that the migration of the radiogenic gases is
coused bY other reaaons, not by the naturd of the atoma
A40 and H94. It is possible that, the nodal vacancies (holes)
shift in the crystalline lattice of the mineral. Their
quantity increasos with the temperature rise. They seize and
"transport" the atoms of radiogenic gases. A certain
difference of the D-value for A and Ile in the carbonaceouo
a.-Usts is apparently due to the occurrence of several phases,
in these rooke in which the gmis may be differently
distributed. The boundary layers botweer the individual phases
are apt to cause considerable losses it, A40 and He4 as well
in the case of low temperatures. The E- ani D-values for

TITLE: Quantum galvanomagnetic effects in n-type InAs
PERIODICAL: Zhurnal eksperimentallnoy i teoreticheskoy finki, v. 41,
no. 602), 1961, 1699-1703
TEXT: Hall effect and resistivity were studied in a. r.-type InAs strong
pulsed magnetic field at temperatures from 20 to 3600K. A magnetic field
of up to 450tOOO gauss was achieved by discharging a 1200-IAF capacitor
block through a beryllium bronze coil. The relative change in resistivity
in a pulsed magnetic field does not depend on the length-to-width ratio of
the specimens where this is greater than 10. The tpecimens studied had

the magnetic field strength UP to 400,000 gauss. At 200K it wao constant
in fields of up to 160,000 g%u%s and then rose slightLy, due to the fact,
that at H >160,000 gauss the activation energy of' th-'3 impurities is
greater than the mean energy of the free slect,-%-is. Therefore, the tk
carrier equilibrium concentration dpersases. In the atrongly degenerate
M-13-type specimens at 200K M-.I! f-cu-stant did not change in a magneti.1-
