symmetrized by means of the Young operator meets the
conditions of Fok. In the reverse direction the relation
is obviously more complicated. The symmetrization by means
of Young operators is then convenient when from a coordinate
function, which in general is asymmetric, a function with
the necessary symmetry properties should be constructed.
When, however, the function is already known it is more
useful to verify, whether the symmetry conditions of Fok

ABSTRACTs The author investigates an n-dimensional -Isotropic oscillator,
the BYBteM of units being chosen in such a manner that the
frequency, Planck's constant, and the mass are equal to I.
The energy gperator of the system then has the form
2 2
and the energy levels
(pk xk
Em m + (n/2) (m 0, 1, 2, ...)of the system are degenerated.
This degeneration is due not only to spherical symmetry of the
system. Short reference is madet to several previous papers
dealing with this subject. In the present paper it is shown
that the definition of the group of the! isotropic oscillator,
which was given with the help of interference operators and
Card 1/3 deriving elements (such as have already previously been
The Symmetry Group of an Isotropic Oscillator SOV/56-36-1-13/62
d.escribed by the author) and G. A. Baker's definition by
means of canonical transformations are equivalent. First,
it is stated 'that the commutation relation between the
infinitesimal operators (derived in previous papers (Refe; 1, 2))
agree with the commutation relations between the infinitesimal
matri-,es of the threedimensional linear unitary group. The
matrix of the infinitely small Linear unitary transformation
can be written down as U = I + AL. Here I denotes the unit
matrix, L - an arbitrary Hermitian matrix, and S - a small
parameter. Next, the commutation relations between the
linearly independent infinitesimal matrices are given. The
symmetry group defined in the dforementioned previous papers
is isomorphic with respect to the unitary group and, consequent).);
also to the symmetry group investigated by Baker. Generalization
for the case n> 3 is trivial. It is then shown that the two
above-named groups are equivalent. The author also investigates
a special case of canonical transformation in which only one
pair of coordinates and momenta is transformed. In this case
it is possible, without a general restriction, to investigate
a onedimensional oscillator. Formulas for the time dependence
Card 2/3 of the wave function of the oscillator are given. In the
The Symmetry Group of art Isotropic Oscillator SOV/56-36-1-13/62
following, another type of transformations is investigated
in which there is participation of 2 pairs of coordinates
and momenta. In the case of the"third type of transformation
investigated, i, e. in the case of a pure rotation, the
correspond.ing component of the angular momentum serves as
infinitesimal operator. Finally the explicit shape of the
kernel is determined (with tin accuracy up to one normalization
factor) for the unitary unit matrix of the transformation.
The isotropic oscillator is, by the way, an example for a
system in which the energy operator is fully expressed by
infinitesimal operators of 1;he symmetry group. In such cases
it is pose~ible, from the synmetry properties of the system
alone, to derive also all its other properties (energy levels,
degree of dageneration, Green's function etc ). There are
4 Soviet references.

possible to break H into a perturbational and a nonperturbational part in
two way-s (H - H1+VI . H2+V 2)1 expressions for a 12 can be obtained in first
perturbation-theoretical approximation, but, as is shown, the uniqueness
of this expression cannot be guaranteed. It is now shown in the present
paper how the formulation of the variational principle is to be altered
in order to guarantee the uniqueness of perturbation theory for an
arbitrary choice of trial functions, and automatic invariance of the ex.-
pression obtained for the transition probability with respect to the
addition of a time function to the energy operator, For this purposed a
new variational principle is obtained instead of (8).

TEXT: By vay of introduction, the author discusses the importance of the
virial theorem in classical mechanics and deals with its introduction into
quantum mechanics. Concerning the problem of the continuous- spectrum of
the energy opera-or the author has been the flz-st to obtain a forn-ola for
the problem of '.~e 3cattering of particles by a center of force,
corresponding to the virial theorem (Demkov, DAN, 89, 249 (1953)). This
formula has been already extended to complicated p7-oblems of the collision
theory (inelastic exchange ,rocesses), to the Dirac equation, and to
problems of the qpantum field theory. A corresponding general4zat4on in
classical mechanics has not Veen undertaken so far. The author uses'a

of the various formulas derived for the calculation of transitions
between neighboring discrete levels. As applied to the collision
between a negative ion and an atom, the calculations are aimed spe-
cifically at determining the probability that the electron will re-
main in the bound state, that is, the probdbility that no ioniza-
tion will take place, and the determination of the energy spectrum
of the electrons produced by the ionization. It is concluded from
the general theory that the average momentum of the emitted elec-
trons decreases slowly with decreasing velocity of the colliding par-.
ticles. For small momenta the emitted electrons have an isotropic
distribution proportional to the square of -thi! momentum. At large
momenta a characteristic exponential distribution is obtained. The
applicability of the theory and the conditions under which the ioni-
zation probability is large is discussed. Although the formulation
of the problem is general and can be applied.to other problems as
well, the results cannot be readily employed for the interpretation
of the experimental data, which are insufficient even for simple

'ABSTRACT: This is a continuation of an earlier paper by the authors
j(ZbETF v. 47, 918., 1964). in which they considered a particle in a
1potential *ell of smill radius (negative ion) Bituated in a strong
~electrie field. The present article deals with the same system, but
'in a uniform magnetic field. 'The case of a shallow potential well is
'first considered, where there is no:bound state in the absence of the
~jfield. It is then pxoved that., for an arbitrary shallow three-dimen-
bional well, a bound state always appears.when an-arbitrarily weak
'field is switched on. In first approximation the binding energy is

,ACCESSION NR: AP5019239
Iproportional to the square of.the field, so t1lat this phenomenon is
Teminescent of diamagnetism, but acts In the opposite direction. The
magnetic field has a stabilizing influence on the particle,, but real
magnetic fields are too weak for such an effe,3t; to be observable with
~free atoms or electrons. It la shown, however., that for semiconduc-
Urs at liquid-helium, temperature and for, electrons or holes with low
'effective masses the binding energy becomes comparable with kT, so
,that the bound state produced may be observed expe rime ntal 1y. If the
potential well is sufficiently deep, so that there is a bound state in
!the absence of the magnetic flold, there is the usual diamagnetic
effect, which increases the total energy by a1.1 amount proportional to
the square of the field and leads to expulsion of the system from the
field. The binding energy of the particle increases with the field.,
so that the magnetic field again exerts a stabilizing influence on
the particle. 'We thank A. G. 2',bili nd A. V Tulub r valuable

ABSMMT: The author describles briefly the quasiEtationary state.Ar which arises
when an electron collides with a molecule AB. It is shown that tmder certain con-
ditions the quasistationary abolecule 0' dissociates not into a negative ion and
an atom, but into the initial moleculep which may remain in an excited vibrational
state,, and an electron with Rower energy. This backward decay gives rise to sev-
eral, iaotopic effecto. In lxLrticular., the crosgi Bection for negative-ion produc-
tion may be much smaller for D,2 then for H2. TMig effect makes -it possible to in_
Vestige.te the sbape and vidt?d of the quasiotatiorviry potential cmr~re for negative
imolecular ions. In view of the great mathematioal difficulties involved in calcu-
lationii for quasistationary states of diatomic moleculesp this effect is regarded
as a moans of more thorough interpretation of the available experimental data#

ABSTRACT: The M'St part of the paper (ZhETF v. 46, 1126, 1964) dealt
with the detachment of an electron in a collision of the type A- + B
under the limiting condition that the system JIB is replaced by an ef-
fective potential. well whose radius is aseumed to be swill compared
with the wavelengt;,b of the emitted electrons. In the present paper
this limitation le, eliminated by replacifig: the system All by an effectLve
potential in the form 'of two wells of a suall radius, using an approxi-
mation recently enjDloyed by 0. B. Firsov and B. M. Smirnov (ZhETF v. 47,
232, 1964). It te assumed that when the nuclei come closer together

the state A2_ vanishes and decays. The angular and energy distribution
of the outgoing electrons are calculated for the symmetrical and anti-
symmetrical states. It is shown that allowance for tbe finite dimen-
sions of the system has an unexpectedly small influence on the energy
spectrum of the electrons. A general system of equations is obtained
for the motion of a particle in the field of small-radius potential,,q,,-,
wells with variable depth. Author thanks 0. F. Drukarev and L. D.

ABSTRACT: The authors conigider the reaction A + B -,- A + Bt + e, in which the atoms
are in the grotu-Ld or in the excited states prior to the collision, but the excita-;

symmetrical model is ana:1,rzed by way of an example. It is shown that the problem
reduces to an analysis of the interaction of the a-bate with an infinite number of
parallel states aM with a continuous spectrum. and the case is considered in which
one energy level of the system, crosses an iVinite system of parallel levels ad-
jacent to the ground state of the system AB . A general mathematical model is em-,
ployed which Vields the wavv function, in the form of a contour integral., for the

is described elsewhere (DAN SSSR, in press), and whose earlier simpler applications
were described by one of the authors earlier (Deiakov, ZMtF v. 49, 885, 1965 and

ionization potential, so that the motion of thet nuclei can be chosen classically
and the corresponding nonstationary problem can be solved. The method can also
be used in a quantum description of the nuclear motion which is required when the

Arsenic Tri-chloride VI
PERIODICALt Chemick'e listy, 1960, No.8, pp.846-849
TEXT: High-purity arsenic is used during the preparation of
semiconductors and also for the manufacture of some intermetallic
compounds of the type AIIIBV. A high degree of purity is
required as it affects the electrical properties of the substances.
Pure arsenic is obtained by the thermal decomposition of arsenic
trichloride in hydrogen. The authors describe an extraction
method for separating traces of admixtures, especially of Sb, Fe
and Cu from the compound. When arsenic trichloride is extracted
with hydrochloric or sulphuric acid, most of the impurities go
over into the liquid phase; arsenic trichloride itself is only
moderately miscible with these acids. The systems HC1/AUCI 3 and
H2SO4/AsCl 'If were found most satisfactory ets they have a
sufficiently high capacity, they have different densities, a
sufficiently high separation coefficient and equilibrium is

admixtures in the upper phase (in weight percent); Table 2
gives results of the spectral analysis and Table 3 the dependence
of zhe number of extraction stages on the separation coefficient.
It was found that high-purity etrsenic containing approximately
10-2% im:purities could be obtained from the starting material by
two extractions only. This process gives a higher degree of
extract�on than that obtained by the distjillation method and can

TITLE: Preparation of highly purified zinc by vacuum
counter-current distillation
PERIODICAL: Chemicke' listy, no.5, 1962, '5311-539
TEXT: A distillation unit from silica glass for the
refining of zinc is described and operational details are given.
The analytical procedures for purity determination of the
refined zinc are based on differential ratos of etching of crude
and refined zinc. The distillation unit is designed for the
refining of 4500-4800 g of zinc. As a laboratory procedure, the
method is claimed to be superior to the refining of zinc by
electrolysis or zone melting. A sketch of the apparatus is
shown in Fig.1, where: A - distillation. flask; B - column,
packed with silica rings; C - inlet tube (for introduction of
molten zinc); D fused-on tube for thermocouple; B - side arm,

ABSTRACT: Gamma spectra of short-lived 05
order to improve or correct existing data, The instruments employod were a 40 x 40 mm
Nal crystal scintilLlation spectromoter with a resolution of 10% at 662 keV and a last-
slow gamma-gamma coincidence spectrometer with a resolving time of 10 nanosec. The
source was the osmium fraction from a gold target bombarded for 30 minutes with 660
MoV protons. Rhenium was repentedly'separated from the osmium source to serve as the
rhenium SDurce. Aaalysis of the osmium decay curve showed the presence of activities
with half-lives of approximately 23 min, 90 min, end 23 hr, Gamma lines with half-
lives less than 2 hr were observed at 120, 190, 240, 310, 510, 800, and 880 keV. It
was not In general possible to assign definite helf-lives to the different lines, but
the decay of the Intense 240,k#aV line was found to be complex with the two half-lives:
^-030 min and 90 J: min. A gamina spectrum recorded 14 hours after separation of the
osmium showed lines at 115, I&D, 385, and 510 keV,, Gamma-garma coincidence measure-
ments were undertaken in the 510 keV region. No coincidences were observed at 900

but coincidences were observed at; 2800. The 520 keV line is accordMagly ascrIbed to
annihilation radiation. Tbb decay of the annihilation radiation was complex, with
half-lives of 23 � 3 min and 3 � 0.5 hr. The rhenium separated from the osmium source,
38 min after beginning of accumulation decayed with two half-lives; 22 i 3 min and
21 1 2 hr. Assoointed w1th the short-lived activity there were observed gamma lines
at go, NU 1 210, 260, 315, 440, 1510, 600, 680, 760, 840, and 940 keV. Associated withi
the long-lived activity there was observed a gamma line at 365 keV; this activity is
accordingly ascribed to ReM. 'rho present data aro cGupatad with the findings of
Yu.Surkov, O.M.Chernov, A.K.Levrakhina, and Z.V.Krovachcako (Izv. AN SSSR. Sorv.fiz.,
24, 119 (1960)), T.V.Mm1ys4Ova, and B.A.Khotin (Izv,, AN SSSR, Ser. Piz., 25, 1256
.(1961)), and I.S.Poster, I.M.Hilborn, and L.Yaffe (Canad. J. Phys.,36, 555 (1958)),
and numerous points of -ag"ement and disagreement axe noted. The principal conclusion
of the ansubg discussioA Is that the gamma spectrum of radioactive oamium is con-
siderably wore complex than was Indicated by the f;Uidijigs of Surkov at al. (loc.cit .
and that further investigation of both the osmium aj2d rhenium activities is necessary.

ABSTRACT: Data on the animal part of a closed ecologiral.system'such as might
be used in spaceflight' (based on unicellular algae, higher plants, animals,
-and man) are presented. Most of the information concerns chickens and
'ducks, good choices because they mature fast, produce a sufficient quantity,
of nutritious food, and have a high yield of meat and eggs per unit of feed.
'Comparative analysis shows that to produce 1 kgr of meat and fat, cattle
;require approximately twice as much feed, and pigs L 5 tinies as much~'

ducks are easily raised by incubating fertillized eggs, and their offspring.
(taken together) weigh more than the offspring of other animals. TIAe meat
of chickens and ducks has more protein and is Q~er.-,vmrl-w;b4ihan the
protein of other animals. Calculati6ns are made of the- number of ducks re-
quired to provide a cosmonaut with his daily requirement of animal protein
(407-15 g), and tables showing turnover of the flock are listed. For instance.-
itwas concluded hat 9 Peking ducks (40 days old) will feed a cosmonaut
for I month. Fifty eggs are needed for food and hatching in the same period.
The daily food and water requirement for this duck population is computed,
together with the amount of respired C02. Analogous comparative data are
listed for chickens. Charts of the nutritive content and caloric value of the
food produced bv chickens and.ducks -are included.

It is c' lculated that for i cal of this food, 25. 4 kcal o e nded.
for zt~ duck, and 22. 2 kcal for a chicken. Of course, the needs of other links
in the closed system will determine whether chickens or ducks are finally
chosen. Both animals have advantages: ducks, for instance, can be fed a

higher percentage of green fodder, and they both mature and gain weight
faster than chickens. It must be emphasized that these are onlV'p'reliminarX
