Abstract - TM' eat exchange interaction in ionic crystals vas calculated vithin th e
scope of a polyelectronic polar model. An ionic lattice of Who type is COA"
sidered, a portion of the latticepoints of vhich in occupied by magnetic
and the other portion by non-magnetic ipns. It is assumed that in the basic
state each magnetic ion has one s-electrOn in the inconple~e shell and each
non-magnetic ion has two p-electrons of opposite spin, Indirect.exchange in-
teraction occurs as a result of the transfer of electrons betwen magnetic
azd non-nagaetic points of the lattice. As a result of expansion of polyele-
.etronic hamiltonian to a series in povers of minor integral of inorthogonali-
ty of atomic veve functionslit is shovn that integral of indirect exchange
interaction differs from zero only at fourth approximation and not at the
third as vas assumed heretofore.

ABSTRACT: The theory of Frenkel as generalised by Galishev and
Vonsovskiy (1) is applied to the investigation of the
mechanism of the absorption of light in crystals. The
probability is calculated of a quantum transition of a
system of electrons from a ground state to an excited
state under the action of light, It is shown that the
optical properties of such a system at absolute zero of
temperature are not fully analogous to the properties of
a system of isolated atoms. In the cases where exchange
effects and pair procepses of excitation can be neglected,
the present theory reduces to Frenkel's theory.
In accordance with refs. 1 and 6, a crystal lattice with
"frozen" positive ions is considered in which non-
Card 1/3 uniformities in electron density are absent, and each
crystal node has a valency electron over the closed shells.

TITLE: On the possibility of spontaneous ionisation in the system
of interacting electrons of a crystal. (0 vozmozhnoy
samoproizvollnoy ionizatsii v sisteme vzaimodeystvuyushchikh
elektronov kristalla).
PERIODICILL: "Fizika Metallov i Metallovedeniye" (Physics of Metals
and Metall 9Y)s 1557, Vol.4, No.3, PP. 392-399 (U.S.S.R.)
ABSTRACT: Fundamentally two approximations are available for solving
the multi-electron problem of the crystal. One is based on
the generalised Geitler-London-Geisenberg model, the other
is based on the model of collectivised electrons. It is
usually assumed that the first model can be successfully
utilised in investigating various properties of the electron
system of crystals of dielectrics and semi-conductors, whilst
the second can be successfully applied for crystals of metals
and alloys. Shubin and Vonsovskiy (1) showed that it is
possible to utilise the first mentioned model for metallic
crystals; thereby,the quasi-classical a-pproximation was
utilised which enabled accurate determination of the relation
,of the mutual distribution of the minima of the energy levels
Card 1/4 of tiae electron system on the number of ionised nodes 2s.
It is shown that only those naive classical conceptions

which do not take into consideration the influence of the
distribution of ionised nodes along the crystal and of the
quantum "energies" could lead toaeJnc=.ect interpretation
of ionised states being unfavourable from the enerLU point
of view. Mott (3) states that for low values of s the
energy of the system increases only with increasing degree
of ionisation owing to increase, of the classical ionisation
energy; only for very large values of s, when screening
starts to play a certain part, does Mott consider ionioation
states as bein[; favourable from the energy point of view.
These qualitative conclusions of Mott are not supported by
calculations. On the basis of results obtained in the above
mentioned earlier paper and one of the authors (1), it is
possilole to plot easily the curves of the dependence of the
energy of the electron system of the crystal on its degree
of ionisation s1N. The authors of this paper investigated
this dependence for various ratios of the absolute values
of the integrals A, I and L and the results are represented
diagrammatically in the Uaph, Fig.l. They consider that,
Card 2/4 eontrary to the view of Mott, states of spontaneous
ionisation are fully possible for low values of s, as is

shown bpmore systematic consideration of the quantum effects.
The problem of determination of the lowest energy state of
a system of interacting electrons within the framework of the
polar mcdel was also considered in the work of Bogolyubov,N.N.
and Tyablikov, S.V. (4,5); they give a quantitative justifica-
tion of the ideas of Mott that the existence of a weakly
ionised state is, from the energy point of view, unfavourable.
Detailed analysis of this problem, given in this paper ., shows
that this conclusion is unjustified. It is concluded that
the distribution of the energy levels of the homeopolar and
the ionised states in a crystal have a direct and complicated
dependence on the ratio of the absolute values of the atom
energies of various types in the crystal, due to the quasi-
classical as well as the specific quantum part of the electro-
static interactions of electrons in the crystal. Therefore,
partial as well as full spontaneous ionisation of the electron
states may occur and it can be stated that the generelised
Geitler-London-Geisenberg model can be applied for explaining
Card 3/4 phenomena relating to the metallic conductivity.
There are one graph and 6 references, four of which are Slavic.

Slater determinant form (Eq.(1.1)) for Frenkel excitons
and analysis (neglecting magnetic interactions) for the
wave-functions and energy is then standard. It is then
shown that the Frenkel excitons can carry no current.

ABSTRACT: A communication is presented on the major directions taken
by the work of the Institute. Theoretical studies are in the direc-
tion of determining interelectronic interactions in solids. Investi-
ga ti on is under way of the mechanism of the forces of cohesion in
various types of solids. Studies are under way in the theory of
the technical magnetization curve and in the physics of ferromag-
netic materials. The electrical and optical properties of metals
are investigated. The problem of the relationship between phase
composition and mechanical properties in metals and alloys is
being elaborated. Bibliography: 28 references,

ABSTRACTs In the present work the method by Bogolyubov-Tyablikov is ex-
tended to the non-steady case of the alternating electromagne-

firat investigated a simple atomic cubic crystal with an
a-eleotron in the s-state in each nodo of the lattice* The
thermal oscillations of the ions of the lattice are neglected.
On this occasion the Hamiltonian of the system of the eleo-

Extension of the Bogolyuboy-Tvablikov Perturbational Method to the Mon-

ed, Then, the perturbational method by Bogolyubov-Tyablikov
is extended to the non-steady case. The computations given
here hold for such light frequencies which disagree with
the fundamental frequencies of the system. The consideration
of damping makes possible the investigation of the general
case with any frequency of the incident light which will be
demonstrated more precisely in a later paper. In the case of
the approximation investigated here the spectrum of absorp-
tion of light through the system of electrons of the crystal
in a discrete spectrum. This moans from the physical point
of view that the "pairs" and "holes" occurring due to the
action of light remain in the bound states and the absorp-
tion of light by the crystal is not photo-electrically ac-
tive.'The last chapter treates the determination of the "de-
formed" current operator. There are 5 references, all of

~On the Problem of the Statistics of Spin- and Polar Excitations

PERIODICAL: Zhurnal eksperimentallnoy i-teoretioheskoy fiziki, 1950j

ABSTRACT: It was proved by some papers (Refs 1-3) that the spin waves
(ferromagnow ) occur not as bosone but as fermions. Also for
the polar elementary excitations (of "twins" and "holes") in
eleotron systems of crystals this question was discussed
(Ref 4)- In.thie connection the question is of interest as to
the statistical classification of ferromagno* andpolar ex-
citation. The present paper deals. with some faults committed
in dealing with the spin- and polar excitations in crystals
which may lead to the occurrence of fictitious states
Refs 2, 5, 6)), and it is shown that if these faults are
~
eliminated$ the spin waves may be assigned to the bosons;
for polar excitation the question is investigated as to when
it is caused by bosons. Further, the question is discussed as
Card 1/2 to how this metbod of second quantization is to be formulated

SOV/56-35-6-19/44
On the Problem of the statistics of Spin- and Polar Excitations in Crystals
if one has a finite number of particles that can be described
by symmetric wave functions (booone). It is shown that quasi-
particles (separable in the system of interaoting crystal elec-
trons) obey Fermi statistics in such cases in which"single
electron transitions" correspond to the solution, and that
they obey Bose (Boze) statistics if "two electron transitions"
play the part of a solving agent in the dynamics of the system.
(correspondingly: half-integral spin --ap- Fermi statistics, in-
tegral spin -30-Bose statistics). The results obtained by this
paper verify the opinion expressed by I. M. Lifshits (Ref 4)
concerning the statistics of "twins" and "holes" at the
Kiyev Conference on Semiconductors (1956). There are 17
references, 7 of which are Soviet.

ABSTRACT: Some authors (Refs 1,3) were very successful in explainine the
microscopic nature of this phenomenon. However, these authors
investigated the properties of weakly interactinf; Cases of
Fermi particl:es (electrons) and Bose particles (phonons) out-
side the binding with the structure of the metal. It is there-
fore interesting to use the multielentronic model of the
metal (Ref 4) in the investigations of this problem. The
authors investigate a system of interacting exteiial electrons
of a crystal. The corresponding Hamiltonian is given explicitly,
after which then it is transformed. In this expression for the
Hamiltonian H one may separate the disturbation due to the
interaction with the phonons. The investigation of the separa-
ted expression for H makes it possible to affirm the existrnee

for the critical temperature is given, A criterion for the
superconductivity is the prevailing of the interaction with
the phonons over the shielded interaction. According to the
con31derations of this paper, it may be assumed that L~ 0
and great values of Z effective are favourable for the existence
ofthe superconductivity. L is a term figuring in the expression
of R. In order to verify this conclusion the authors computed
Teff -according to Slater's (Bleter) method and found the
following result: For every superconductor with the exception
of Nb (z effective ' 2.8.) the inequation Zeff.,~3 holds good.
The maximal value of N of all the superconductors was found
for Bi (Z effective ' 6. 5. The upper limits of Z effectille in
any period are determined by the superconductors.. 71ithin the
ind.ioated limits the following metals are non-superconductive;
Pe, Co, Ni, Cu, Rh, Pd, A-v, Wf Ir, Pt, and Au.. The above

A13STRACT: It is interesting to investigate this problem from the point
of view of the new microtheory of superconductivity (Refs 21
3, 4) where the peculiarities of the energy spectrum of the
external (a) electrons have to be taken into account. These
peculiarities may be considered, for instance,-in the (a-d)
exchange model of the ferromagnetic metals. (S. V. Vonsovskiy,
Ref 5). At T = 0, in the no4mal state of the ferromagnetics,
there are 3 regions in the k space. (k denotes the wave vector).
In reCion I there are equal quantities of spina of the 2
possible orientations. In region II there are only a-electrons
of the left spin orientation, and in region III there ai:e
Card 1/2 only holes. The following conclusions may be drawn from the

SOV/20-122-2-11/42
Concerning the Problem of the Absence of Superconductivity in Ferror-agnetics
calculations discussed in this papert From the point of
view of the new microtheoryq the absence of the supercon-
ductivity in the ferromagnetics is an internal property of
the system of its electrons. This property is caused by the
relatively strong (s-d) exchange interaction. The supercon-
ductivity, therefore, can be observed only in those forro-
magnetic metals which have a very weak 0-d) exchange inter-
action. There are 13 references, 8 of which are Soviet.

PERIODICAL: Zhurnal eksperioentallnoy i teoreticheskoy Miki, 1959,

ABSTRACT: A. number of papers is first discussed which deal with the
microtheory of superconductivityq and the assumptions
-concerning the nature of the statistics of the elementary
current carriers are discussed. Whereas in some cases
Fermi statistics is used, the majority of authors work with
Bose or Bose-Einstein statistics. In the present paper the
authors investigate a system of charged Bose polar
excitations by means of the method employed by Bogolyubov
for analyzing the superfluidity of a woakly non-perfect
Bose-Einstein gas. The possibilities for a superconductive
state in metals was investigated for the case in which the
elementary current excitations of the electron system are

of the"polar" many-electron crystal model. Criteria are
obtained for the possible existence Of a Bupraconductive
state in the system of charged bosons: low temperature,
amall thickness of the quasipartioles, practically no
"aingle-electron" transitions,and negative Bign of the
exchange integral. The phonon-induced interaction between
the current Bose particles is of an attractive character
and impedes the occurrence of the superconductivity of the
latter. The dependence of the critical temperature of a
slaperconductor with Bose current carriers on the isotopic
aLiss of the crystal ions differs from that of a metal
with a Fermi electron spectrum. This difference can be
used in order experimentally to divide the superconductors
in to such of Fermi- and such of the Bose type, There are
14 references, 10 of which are Soviet.

TITLEs Many-electron Theory of Ion Crystals
PERIODICALs Flmika tverdogo tela, 1960, Vol. 2, No. 8, pp. 1793-1805
TEM Ion crystalsare characterized by strong inhomogeneities of the
electron density at neighboring,lattice points. The binding forces have,
therefore, essentially an electrostatic character. The interaction of
electrons with one another and with lattice vibrations must be taken into
account in the theory of ion crystals, Such studies were made earlier by
S.: I. Pekar (R*ef. 1). In the present paper, the authors describe the
investigation of ion crystals (phenomenological and model treatment)
within the framework of a many-electron theory by means of the method of
elementary excitations. The approximation used here is valid only for
weakly excited states of the many-electron system. A consistent handling
of the problem by quantum mechanics is possible only under this limitation.
When the excitation is weak and an energy gap exists, it is possible to
separate the enorgy spectrum in good approximation into individual branches

TEXTs In the eloctron spectrum of metallic crystals which are composed
of elements of the transition group and of the rare-earth group, special
properties are observed compared to the crystals e%f other metals. This is
brought into conpection with the d- and f-shelle of the electron sheath.
The electron deniiity of the transition metals is divided into 'three
regions. The firs,t is near the nualouag the second consists of the valence
eleotronsp and the third intermediate region consists of the electrons of
the non-closed shells. For this system the Hamiltonian (1) is written down.

:
tatistioal Greea function developed by N. N. Bogolyubov and S. V.
Tyablikov (Ref- 7)- The development of the distribution functions of the
Bose- and Fermi particles is dealt with in detail, and formulas (11) and
(12) are obtaine,i. As turned out in the course of a further investigation,,
the exchange int-3raction between the outer and inner electrons leads to
an exchanqe coupling between the inner electrons. As may be seen from
formulas (18) and (19)v this interaction has the character of a ferro-
magnetic coupling. If a direct d-d exchange-of the inner electrons is
lacking, this lelLds to ferromagnetism. Indirect interaction by conduction
electrons leads only to the renormalization of the exchange integral and
does not change the energy spectrum of the spin waves. Yo. A. Turov,
