.Abstract In the preseatcommunication the writer. presents the results of cal-
culations of the relative intensity of groups of alpha7.particles in'..
RdAc 4AcX on the basis of model of nuclear rotators,(S. G. Ryzhanov,,
-e.ti
ibid.) 23, 417, 1952), and compares with experimental data of Ras.tt.
Hans Bethe (1940), at.thebasIs.of the computations being the
quantum-mechanical theory:of alpha-decay as expounded in the mono-'.-
g-raph of Bethe. The writer concludes that the possibility of
theoretically. interpreting the large experimental material on alpha
and gamma,siectra of essentially radioactive elements on the basis,of
the scheme of nuclear rotators indicates that this schemeis,not de-
void of theoretical,interest. Ten.referenc6s: e.g. S. G. Ryzhanov

Here a connection between the deformation of the surface of the nucleus and the
relative intensities of the a-groups in composed ci-spectra.of.radioactive nuclei
is described. Computation results were then.applied to the a-spectrum of,RdAc.
The following factors act upon the intensity of the a-groups,: The~ex ponential'..,..
factor in the-well-known formula by GAMOW-BETHE, from which there results them..
transmission coefficient of the a-particle through thelpoten'tial barrier,.and.a...~

vestigation: (the energies of the levels were taken from Ref.1).

1. The levels 59 6 and 332 KeV are one-particle-levels.
2. The levels 11o, 173, 238 are probably rotation satellites.of
the level 59 KeV.
3. Thek-transition of 50,2 KeV is correctly ascribed to a, tran
sition between the levels,286 and 238 KeV. There are I table
and 5 references, 1 of which is Slavic.

ABSTRACT:- A hypothesis is advanced that the nucleons in medium.and heavy nuclei'
are separated into three layers (corresponding to the magic numbers 28, 50, and 82),
each of which has Its own deformation and,moment of inertia.. ~ A number of consi-
deratiofis is advanced with respect to the.dennity distribution in the nucleun.and-
pair1correlations.1between nuclei in order to justify thishypothesis. A formula,
~is:obtained for the energy of the rotational levels of the.nucleus in such a model,

ABSTRACT: The paper deals with the effect of pressure on ordering In AuCua-type alloys
in, which the transition to the ordered state Is a first-order phase transition. Theoretical
analysis of the equilibrium..conditions in a binary alloy A-B of this type shows that the pres-
sure does not affect the magnitude of the jump in the degreeof long-range order at the,
transition point; pressure only shifts-the transition point To to lower or higher values.
Analysis of the effect of pressure on the degree of long-range order is also carried out for
an alloy of stoichiometric composition. It. is pointed out that for many metals and allo
ysV
the decrease of compressibility with pressure becomes appreciable at pressures of about
4 a

.Abstract In the preseatcommunication the writer. presents the results of cal-
culations of the relative intensity of groups of alpha7.particles in'..
RdAc 4AcX on the basis of model of nuclear rotators,(S. G. Ryzhanov,,
-e.ti

Hans Bethe (1940), at.thebasIs.of the computations being the
quantum-mechanical theory:of alpha-decay as expounded in the mono-'.-
g-raph of Bethe. The writer concludes that the possibility of
theoretically. interpreting the large experimental material on alpha
and gamma,siectra of essentially radioactive elements on the basis,of
the scheme of nuclear rotators indicates that this schemeis,not de-
void of theoretical,interest. Ten.referenc6s: e.g. S. G. Ryzhanov

Here a connection between the deformation of the surface of the nucleus and the
relative intensities of the a-groups in composed ci-spectra.of.radioactive nuclei
is described. Computation results were then.applied to the a-spectrum of,RdAc.
The following factors act upon the intensity of the a-groups,: The~ex ponential'..,..

transmission coefficient of the a-particle through thelpoten'tial barrier,.and.a...~

1. The levels 59 6 and 332 KeV are one-particle-levels.
2. The levels 11o, 173, 238 are probably rotation satellites.of
the level 59 KeV.
3. Thek-transition of 50,2 KeV is correctly ascribed to a, tran
sition between the levels,286 and 238 KeV. There are I table
and 5 references, 1 of which is Slavic.

ABSTRACT:- A hypothesis is advanced that the nucleons in medium.and heavy nuclei'
are separated into three layers (corresponding to the magic numbers 28, 50, and 82),
each of which has Its own deformation and,moment of inertia.. ~ A number of consi-
deratiofis is advanced with respect to the.dennity distribution in the nucleun.and-
pair1correlations.1between nuclei in order to justify thishypothesis. A formula,
~is:obtained for the energy of the rotational levels of the.nucleus in such a model,

ABSTRACT: The paper deals with the effect of pressure on ordering In AuCua-type alloys
in, which the transition to the ordered state Is a first-order phase transition. Theoretical
analysis of the equilibrium..conditions in a binary alloy A-B of this type shows that the pres-
sure does not affect the magnitude of the jump in the degreeof long-range order at the,
transition point; pressure only shifts-the transition point To to lower or higher values.
Analysis of the effect of pressure on the degree of long-range order is also carried out for
an alloy of stoichiometric composition. It. is pointed out that for many metals and allo
ysV
the decrease of compressibility with pressure becomes appreciable at pressures of about
