ABSTRACT: Theoretical paper. It is assumed that the solute molecules
do not form covalent bonds with those of the solvent. The sol-
vent is taken to be non-active and transparent in that region
of frequencies where the solute absorbs light. S.I.Pekar's
method (Zh.Eksper. i Teor.Fiz.,Vol.22,641,1952) of adiabatic
approximation is employed. Nuclei of the solvent molecules are
regarded as a "slowly moving" subsystem which executes small
oscillations about certain equilibrium positions. The valence
electrons of the solute molecule are regarded as a "rapidly
moving" subsystem. It is assumed that the electron states fol-
low adiabatically the comparatively slow motion of the solvent
nuclei. Perturbation theory is used to obtain the ener& state
of the solution. Only the average effect of thi solvent on the
solute molecule is taken into account. This,is permissibl~i for
those molecules which are only alightly deformed en interaction

solution is then considered. The interaction operator is
regarded as a small perturbation of the solution which causes
a transition of the solution from its ground state (defined
as the state in which a solute molecule is in its lowest
energy level) to an excited state (a solute molecule is now
in its first,excited level). Average values of the dipole
electric and magnetic moments induced by light are obtained.

ABSTRACT: There are two theories of the luminescence mechanism in
mixed organic phosphors, such as anthracene in
naphthalene or anthracene in polystyrene. Birks (Ref.5)
suggested radiative mechanism with luminescence of the
admIxture being due to absorption of luminescence of the
basic substance. A radiationless mechanism was suggested
by others, with transfer of energy achieved by resonance
interaction between excIted . molecules of the basio
substance and molecules of the admixture. This paper
is an attempt to elucidate theoretically the role of
both these mechanisms at various admixture concentrations.
The total quantum yield (Eq.22) is obtained as the sum

luminescence. It was found that as eoneentration of
admixture is increased the quantum yield due to radiative
z9ohaniam. JJI begins to fall while the quantum yield due
to the radia ionlesa mechanism J I continues to increase
until saturation is reached. This supports the eon-'
oluaion reached in Refs. 6-8 that Birks' meohani= holds
only for low admixture concentrations. At very high
admixture concentrations a concentration quenching effect
occurs and the total quantum yield begins to decrease.

ABSTRACT: A phenomenological exciton theory of molecular crystals
(Refs.1, 2) gives the relationship between the duration of
fluorescence, coefficient of re-absorption, length of
diffusion displacement of exciton and absorption coefficient
of the incident light. For many molecular crystals it is
possible to regard fluorescence transitions as occurring
from exciton bands which correspond to the lowest level of
excitation in an isolated molecule. To determine
fluorescence yield it is therefore sufficient to know
exciton density in the energy bands which correspond to
the lowest levels of excitation. The number of such
bands is equal to the number of molecules in a unit cell.
The width of such bands is about 0.05 eV. Bands can,
Card 1/2 in general, overlap. If they do not overlap, the width

of forbidden intervals between the bands is about 0.01 eV.
At room temperature thermal motion causes blurr.ing and
diffusion of such bands. As a result an electron-
vibration-rotation band is formed in place of the exciton
bands. By a purely mathematical argument the author
finds the quantum yield Q for this particular case
(Eq.16). To determine Q it is necessary to measure
duration (lifetime) of fluorescence at very large and at
very small values of the coefficient of absorption-of the
exciting light, and to obtain the relative distribution of
fluorescence in thin crystals, where re-absorption of lighLt
can be neglected. There are 4 references, all of which
are Slavic.

ABSTRACT The energy dependence of the real part and the imaginary
part of the effective potential is investigated here by
taking account of all components of the oompound nucleus.
For the purpose of not complicating the problem by taking
account of COULOMIS inte'raction, the authors here in-
vestigate only the interaction between one neutron and
one nucleon.
The dependence of the real part of the optical potential
upon energy: At first the formula for the real part of
this potential is given. Next, the authors determine the
energy dependenoe of the relative motion of the mean value
of the real Dart of the optical. potential. The authors are
interested here in the domain of energies which correspond
to the resonances of the cross sections of the nuclear

SOV/3898
The'authors present a simplified method for approximating the
temperature fields and stresses in a drum-type turbine rotor.
The method does not take axial variation of temperature into
account but considers each section of the rotor as p4rt of an
iffinitely long hollow cylinder with boundary conditions cor-
responsing to those for the particular section under considera-
tion. Results calculated by the approximate method are compared
with those determined by more accurate calculations. An analysis
of the discrepancies leads to the conclusion that the simplified
method is sufficiently accurate for most engineering purposes.
