ABSTRACT: The author investigated the stability of a plasma with re-
spect to initial fluctuational disturbances in the stationary
distribution functions f.~ (_fl) of the electric field E and
magnetic field H in the case of high frequencies. Linearized
Boltzmann equations without collision terms are used for the
variations of the distribution function bfi (where index i
denotes plasma components). It is assumed that the intensity
of the magnetic field H is high and the free path of part-
icles composing the plasma is by far longer than the Larmor
radius. The functionts sought for f (*50 by expansion by in-
versed powers of the magnetic field H. The method proposed
is demonstrated by an example of a system with an inter-
mediate curvature of the magnetic field. The article con-

ABSTRACT BRUCKNER and WATSON, Phys.Rev. 102, 19 (1956) investigated some types of
instability for the case that the density of plasma is low and that col-
lisions can be neglected. Boltzmann's equations linearized on this occasion
are used for the perturbations of the distribution functions without
taking collisions into account. Such equations are also used by the author
in this work, for he assumes that the processes leading to instability oc-
cur durin- a time that is essentially shorter than the time of the free
length of path of the particles. Furthermore the author assumes that the
initial perturbations occupy only a small volume compared to the dimensions
of the system and occur at a sufficient distance from the boundaries of the
plasma. Also no boundary-conditions need then be considered. Thus the
author restricts himself to the investigation of a local instability which
might occur in consequence of the directed velocities existing in the
plasma and in consequence of inhomogenities of density, temperature and
the magnetic field.

TITLE: The Ther-modynamics of Superconductors (Termodinamika sverkh-

PERIODICAL: Doklady Akademii nauk SSSR, 1958, Vol 122, Nr 6,, pp 999-loo2
(USSR)
ABSTRACT: The present paper investigates the thermodynamics of super-
conductors by means of Fr8likh's hamiltonian, in which
electron-phonon interaction is explicitly taken into account.
The thermodynamical perturbation theory is used for this pur-
pose. Also the electron-phonon interaction constant is re-
normalized according to the method developed by N. If. Bogolyubov,
whereby it is possible to improve development convergence.
In this way the same advantagesare obtained as in the case of
zero temperatures. The initial hamiltonian is first written
down explicitly. The cBnonical operator transformations are
carried out like In the latporn by N. 11. Bogolyixbov. Noxt, the
hamiltonian is written down by using the now operators (ob-
tained by transformation). The thirmodynamic potential Q is

in which connection the ansatz + < R ) is used. Ex-
pressions for 9 0 and < R> c and (in second approximation)
a rather voluminous expression for 9 are derived. The energy
of the elementary excitations of fermions and bosons are de-
termined by the exclusion of certain graphs, which are given.
The equations given here, together with the expressions for
elementary excitations and with the condition for determining
the chemical potential fully determine the coefficients of the
initially given canonical transformations. As usual, these
equations have a "normal" and a non-trivial solution for the
superconductive state of the system. Finally, the thermo-
dynamic functions are calculated. The authors thank N. N.
Bogolyubov, Academician, for his useful advice, and V. A.
Moskalenko for discussing this paper; they further express
their gratitude to C. Bloch (K. Blokh) for placing the first
printed copy of one of his papers at their disposal. There
are 1 figure and 6 references, 4 of which are Soviet.

TEXT: The authors consider a system of Fermi particle ith direct inter-
s
action. For the fundamental magnitudes characterizing the system the authors
obtain equations, as they occur in the theory of superconductivity under use
of the quaternary hamiltonian in which the interaction of the electrons
through the phonons of the grid is replaced by their direct interaction, or
in the investigation of the nuclear material with the aid of the quaternary
hamiltonian.-In (Ref. 1) and (Ref. 5) there were solved similar equations
under the assumption that the matrix element of the interaction is constant
and.only different from zero in a close neighborhood of the Fermi surface.
In the present paper the authors show that by application of solution methods
for non-linear integral equations with branching it is possible to determine
the.solution of these equations under more general assumptions on the kernels
of the equations. - There are 11 references, 9 Soviet and 2 American.

TEXT: The present article Is a translation from the Russian by F,.Bartels.
The author studied the convectional instatilities of a plasma which are

due to local inhomogeneities of density. pressu-re, magnetic geld, and
other zarameters. The calculations are approximative assuming the
pertuAations to oc--ur in a vclume that is small as compared to the

conductive fluid, (the model of a plasma) in a straight magnetic f-.eld
Is discussed from the viewpoint of magneto-,hydrodyriamics,. In ths case,
instability is due to gravity, Instabilities of a conductive fluid in a
curved magnetic field have been studied in detail by Kadomtsev (RP-f.- 5),
nevertheless, the author derived the stability condition for this case as

well,, In the following a plasma is described by the hydrodynamics of a
two-component system which consists of positive and negative ions. In the
adiabatic case, neglecting friction between the components and aasuming
isotropic pressure with only electromagnetic forces acting upon the
particles, fluctuations of density, pressure, and the magnetic field do
not lead to an instability.. Next, the influence of heat flow upon
convectional processes in the above two-component plasma is investigated,
The heat flow is found by solving the Boltzmann equation by expansion into
powers of !/H. Maxwellian distribution for the particles is assumed in
zeroth approximation, The collision terms in the Boltzmann equation are
neglected, Last, the rarefied plasma is described by the kinetic equations
with the distribution being different from the Maxwellian. In conclusiGri,

TITLE: An Asymptotically Exact Solution of the Model Hamiltonian

PERIODICAL: Zhurnal eksperimentallnoy i teoreticheskoy fiziki,
1960, Vol. 39, No. 1(7)~ PP- 120-129
TEXT: Using the model Hamiltonian by Bardeen, Cooper, and Schrieffer the
authors have shown in a preceding paper (Ref. 1) that the thermodynamic
functions of a superconducting system of the volume V are asymptotically
exact if V --* oo and NIV - const (N - number of particles). This was ex-
plained by the fact that each term of the perturbation-theoretical expan-
eion, by means of which the correction to the solution was calculated, be-
comes asymptotically small when V --w co. The present paper shows that an
asymptotically exact solution as the one given in Refs. I and 2 is obtained
even if perturbation theory is not employed. It is further shown that the
solution resulting for V - oD 9 which corresponds to the non-supercondue-
tive state (trivial solution), is not applicable at temperatures, 9, below

that of the phase transition, 0 0 , as it does not satisfy the conditions
required for exact Green functions. It has already been said (Refs. 4 and
5) that there is no trivial solution for 9 < 0 0 . The authors first give
and discuss the model and approximative Hamiltonians of the theory of super-
conductivity. The second part of the present paper shows that the whole
chain'of equations constructed for Green functions on the basis of the
model Hamiltonian can be satisfied asymptotically. The last part shows that
the trivial solution cannot be used below the critical temperature as it
does not satisfy the conditions required for exact Green functions. A sum-
mary of the results of this work is given in conclusion. L. N. Gor1kov is
also mentioned. There are 11 references: 7 Soviet and 2 US.

TITLE. On the Problem of the Convective Instability of a Plasmall
PERIODICAL: Doklady Akademii nauk SSSR, 1960, Vol 130, Nr 21
pp 295 - 298 (USSR)
ABSTRACT: In a previous paper (Ref 1) the author investigated the con-
vective instability of a plasma (caused by the spatial in-
homogeneity of its parameters) on the basis of the kinetic
equations without considering particle collisions. The pre-
sent article deals with the same problem on the basis of
simpler hydrodynamic equations. The author confines himself
to an investigation of weak disturbances without considering
boundary conditions, which fact is justified in atudying con-
vective instability. First, he uses an infinite-conducting
fluid described by the equations of magnetohydrodynamics

(u\7)H - H div u. The fluid is assumed to be homogeneous
along the magnetic field. Furthermore, iN_ it holds (where _9P
denotes gravitational acceleration), and the magnetic field
is assumed not to be curved. The stability is investigated
in linear approximation, and the disturbances are assumed to
be small compared with the steady values of the respective
quantities. Next, equations for the disturbance are written
down. The gradients of the steady quantities are proportional
to a small parameter/t. The condition

As the condition of convective stability for a system
that may be described by the above-mentioned equations. The
convection is caused by gravitation; howeverp if the latter
is ignored, the equilibrium condition assumes the form

plicated case of a binary system in adiabatic approximation
(without considering heat flows). With the help of the afore-
mentioned method it is shown that such a system is instable

disturbances are written down, and are solved by expansion
into the small parameter /L.After carrying Out several oper-
ations, equations are obtained that describe two types of
motions. The system described by these equations is im-wtable
if a current TO - -en 0V0 is present only in the steady case.
Finally, the effect upon convection processes due to heat
flows is taken into account. In this case it is possible to
linearize the equations and to expand them into a small para-
meter. Owing to the drift-like heat flows, heat instability
is possible in this case, which was lacking in the afore.-
mentioned case. The condition of stability has the form

the case of strongly dilute plasmas, i.e., the Maxwellian
distribution was employed as zeroth approximation with Te-
spect to 1/H. A -more exact investigation is pointed out.

TITLEs The theory of a n6nideal Bose gas at non-zero temperatures
PERIODICA: Akademiya nauk SSSR. Doklady, v. 143, no. 4, 1962, 632 - 835
TEXT; N. N. Bogolyubov has developed the theory of a nonideal Bose gas
at zero temperature (Izv. AN SSSR, ser. fiz., 11, 67 (1947)). By-means
of two-time temperature functions a method is given to investigate a non-
ideal Bose gas at non-zero temperatures. Green's functions are derived by
calculating matrix elements by means of perturbation theory. The matrix
elements satisfy the condition that no forbidden bands should be in the
spectrum of elementary excitations. Thanks are due to Academician N. N,
Bogolyubcv, D. N. Zubarev and S. V. Tyablikov for discussions.

ABSTRACT: An approximation procedure is presented in which the speeds C, and C2 of
"ordinary sound" and "second sound" are computed for the case of a condensed system of
I
ibosons. The Green function approach is used throughout. It is found that in this ap-
iproximation, one loses the attenuation of the second sound and also the correction to
!the effective mass of the particles. This ineans -that the interactions between the bo-
~sons must be regardba as weak, and that the particle density is high. The final
I ex-
'pressions for the speed C1 of ordinary sound and -the speed C2 of second sound have the
1properties that (a) C1 is independent of the temperature in this approximation, (b) C2.

ABSTRACT: A method has been developed whereby small amounts of U can
be deposited in the presence of Nb and Ta. Precipitation is car-
ried out in tartaric acid solutions containing Nb.05 )Ta.05, and
UOzC1 2* The U is first reduced by an amalgam of Zn, a collectcr
is added to it [ I cc of 2 percent solution of Zr (N03)41 and both U
and the collector are precipitated by a 10 percent solution of
(NH4) , HPO 4' After dissolving the precipitate in a 10 N solution
of H25,64 . the U is titrated with an 0.01 N solution of NH4VO3
with phenyltranyl acid. Final separation is achieved when the con-
centration of the tartaric acid is 0.5 g or less for every 100 cc of

ABSTRACT: The problem of the amperometric titration of uranium has not
been satisfactorily solved. The polarographic char4cteristics
of elements which can be used as oxidizing agents for the ti-
tration of tetravalent uranium were traced out. A method for
the amperometric titration of uranium with trivalent iron was
also described in publications (Ref 1). The authors of the
present paper used ammonium metavanadate as oxidizing agent
in the titration of tetravalent uranium. Vanadium is on this
occasion reduced to the tetravalent stage at a dropping-mer-
cury electrode at a potential of - 001V. Syrokomskiy (Ref 2)
suggested a visual method of the vanadometric titration of te-
tid.valent uranium with phenylanthranilic acid. This method is
very sensitive, but it can only be employed in 5n - 13,5n
Card 1/3 sulfurio, acid solutions; besides visual methods are unsuitable

for the titration of colored solutions. It became evident that
for ammonium metavanadate in In H 2s0 4' 1n HC1 and In RC104 the
limit current for vanadium is distkutly marked. When using
these acids as medium, uranium can beamperometrically deter-
mined in a potential domain of 0 to -0,16 V.. Before the titra-
tion a hydrogen current was for 30 minutes sent through the so-
lution for removing the oxygen. A change of acidity of 4.1- -o-
lution in a aomain of 0 in to In (sulfuric acid, hydrochloric
acid or perchlorio acids practically exerts no influence upon
the results of titration. Thus uranium in concentrations below
255 7/ml can be determined with satisfactory accuracy by am-
perometric titratija with a 0,005n solution of ammonium meta-
vanadate, The relative error on the averare amounts to 1-'~%~
In titration with a more diluted solution of ammonium meta-
vanadate the titration curve takes a much steeper courne,which
leads to higher errors in the determination of the end point.

thophenantroline. This binds ions of bivalent iron to a stable
bright-red complex which is not oxidized by pentavalent vana-
dium. Iron, prior to its masking, is reduced by liquid zinc
amalgam in a sulfuric acid solution. The mean error of the am-
perometric determination of uranium in the presence of com-
plexly bound iron is 3-6%. For binding lead, bismuth, chromium
and nickel, which elements may disturb the determination by hy-
drolysis or the formation of sulfates, difficult to solve, com-
plexon III is added to the solution. This keeps these elements
complexly in solution and does not influence the results of the
amperometric determination of uranium. There are 2 figrarea, 6
tables, and 2 references, 2 of which are Soviet.

AIIS:L'RACT: Natural uraninites contain relatively small quantities of
thorium. The authors employed anthranilic acid for the
separation and determination of thorium. It was found that
under certain conditions thorium can be precipitated
quantitatively with anthranilic acid. An excess amount of
reagent does not disturb the separation. The optimum Pic value
for the separation of small quantities of thorium in the
presence of uranium is 4.2 - 4.4)uranium being maintained in
complex state in the solution by the aid of hydrochloride of
hydroxyl amine. In this way also rare earths up to a ratio of
C602 : ThO 2 = 8 - 1 and lead are fully maintained in the
Card 1/3 solution. Thorium can be precipitated quantitatively, if its

conceri+r"sion is not smaller than 0.2 mg/50 ml. To determine
thsrium af ter its Lion as anthranilate, the amino group
of anthranilate is diazotized and coupled with ~_naphthol, in
which connection an orange-hued dye is formed.(Ref 8). In this
way, -the application range of this method can be considerably
widened. The colorin-- of the solutions is determined photo-
metrically. The determination of the ThO 2 content is carried
out on the basis of a calibration curve. The error of this
method is sensitivity is very high, and permits the
determination of 0-04rTh/ml. This -D." Qorium separation
and determination was tested on natur~-.l urkninitea,.
A comparison of the results with those the
determination of thorium by the aid of phenyl acetic acid
showed a good agreement. The calibration curve for the photo-
metric determination of thorium is illustrated. The procedure
followed in the determination is described in all details.

ABSTRACT: In the present paper the authors investigated the influence of
iron upon the precipitation of palladium from hydrochloric, sul-
furic, nitric and chloric acid solutions of different concentra-
tion. It was first determined how far the acid concentration may
be varied without decroasing the yield in palladium. The experi-
ments indicated that the precipitation of palladium with d.-methyl
-
glyoxime is still almost complate in 1.5 normal chloric acidq
nitric acid and hydrochloric aci,! solutions. In sulfuric acid
solution a 100%. precip-ibation of palladium still takes place
from the 2-n solution. The increase "in acidity of the solution
influences the yield in pallad-Jum most in chloric acid and least
in sulfuric acid solutiont3. The reoults obtained in the precipita-

Table 2 presents the results of the precipitation in the presence

sults in the presence of trivalont iron in chloric acId nedium.
The results obtained permit the assumption that there is an
interaction between dimethyl glyoxime, iron (III) and p:~.lladium
in acid solutions in which conriection a complex compound is
formed. The nature of this compound is not yet clarified. At
present the authors are carrying out the spectroscopic investiga-
tion of the system palladium-iron-dimethyl glyoxime. There are

j about 200C. optimun, extraction conditions! the v6lum6'df'ether
should equal 'the volume of the aqueous phase, the concentration
of thorluni should be of the order of 1 mg per 20 ml of the
solution. It 'was found that the precipitated thorium
phenylacet-ate possesses specific properties, namely it is
extracted by some organic solvents without changing its structure,
i.e. without dissolving in the organic phase. A complete
extraction of thorium phenylacetate with diethyl ether takes place
in the pH range of 3 - 5. From the organic phase thorium can be
quantitatively re-extrncted with dilute (1:10) mineral acids. The
dissociation constant of phenylacetic acid and its distribution
constant be-~ween diethyl ether and water at an ionic force of the
solution'equal 2 and a temperature of 200C were found to.be

and 311 + 2 respectively. On studying the
possibility of the separation of thorium from uranium, it was
established that from a solution containing 0.1 M of phenylacetic

However, if uranium is present in
~i, larger quantities, the extraction of thorium is difficult,
therefore the method of direct separation of uranium and- thorium by'
,1~~extraction of thorium phenylacetate with ether is'-limited to
similar concentrations of thorium and uranium. 'At higher
concentrations of uranium a satisfactory separa7tion can be obtained'
in the presence of hydroxylamine (for.combining uranium into a

TITLE: Study of the possibility of extractive separation
of thorium from some other elements by the method
of radioactive tracers
PERIODICAL: Radiokhimiya, vA, no.2, 1962, 184-188
TEXT. The authors aimed to develop a method giving a more
complete separation of Th and the rare earth elements than that
described previously by them (Ref.l: Hadiolchimiya, V.2, no.2,
1960, 222) by considering the possibility of preventing
coprecipitation during the extraction. It was found that Th can
be quantitatively separated from La by extracting thorium
phenylacetate with ethyl ether in the PH range of 3 to 4.5.
The separation of Th from large amounts of Ce can be achieved
successfully by extraction in the presence of hydroxylamine.
Correct PH for the extraction depends on the ratio ofCe to Th
and tends towards the lower (acid) values when the ratio
increases. Many cations including K, Nal Hg?-'. Pb2+ and some

others do not affect the extraction. Certain cations such as
A13+ and pe3+, even in negligible quantities', make the
extraction more difficult especially at higher than 4 values of
pl-1. It is therefore necessary to remove both Al and Fe from
the mixture before the extraction. The new method is suitable
for a rapid and complete separation of small quantities of Th
(of the order of 2 mg) and gives a possibility of carrying out
a volumetric finish. The authors intend to apply the method
for the determination of small amounts of Th in various mixtures
containing U, and the rare earth elements.

properties of the entire chemical system enclosed between $the
electrodes become manifest. Measurements were made with an Instlru-
meni ot the Pungor system. The capacity of the titrimeter---t-Oi(ither-
.with the mixer motor was 48 watts; the working frequency was up-
,wards of 100 megacycles. The experimental condit-ions were as
follows: 10 ml of 1-10-2
I X GeO2 solution was poured Into a cell,
and then solutions of pyrocateehin or pyrosallol were added until
~ditferent ratios of germanium to polyphenol concentration were
attained, from 1:1 to 1:200. The volume in the beaker was brought
tb 70 ml in order that the level of the solution would be above
the upper edge of the electrode. This was necessary to eliminate
the effect of variation in solution volume on microammeter read-
ings. The resulting mixtures were titrated with 0.1 N NaOH solu-
tion. Another series of experiments were conducted In parallel,
using the potentiometric titration of germanium compounds with
polyphenols, employing a glass electrode. Measurement of solution'
solution PH values were made on the LP-58 pH-meter, calibrated
,,wit4respect to a saturated solution of Potassium carbonate with
PH = 3.59
As a result of the titration using sodium hydroxide, curves were
tobtained which had.sharp points of Inflection. Beginning with a
