TENT: To confirm the investigations with isomer Bi210
reported by L.I.Rusinov, it was essential to obtain a s~mplo of
Bi containing a large quantity of the isomer and a minimum quantity
of other radioactive admixtures. The-metallic Bi subjected to
irradiation was thoroughly purified from Po and the elements
activated by neutrons Zn, Ag, Cd, Co, Sr, Sb,. So, To.
A sample of Di enriched ill B1210 was obtained from the purified Hi.

ABSTRACT: Numerical values for the above coefficients appear in
calculations for the second differential-s of 11-le Eravi-
tational. potent--al. Thej can be det-rmined from measure-
ments of the beam, etc. before assemblage. The present
article describes a method i-,hich does not necessitate such
measurements and enables the a-.aratus constants to be
measured directly.
K , the moment of inert-la, is obtained fron visual
observations on the period of the beam, and 12 , the
rotational. moment, is obtained from K usinC transition
coefficients. These coefficients are obtained fror the
basic integral equations for K 3nd Y,

TEXT: The following improvements were introduced into GAK-ZM gra--
vimeters in order to increase their quality: 1) Careful temperature
calibration of the quartz system, which allowed the tem erature co-
efficient to be roduced to 0.3 - 0.5 mill~gal/degree; 2~ increas-
ing the syutem's heat protection and the framole.heat capacity;
and 3) increasing the strength of the gravimeter's design and'de-
creasing its weight. The improVemente fulfilled allowed a survey-
,ing accuracy of +0.06 milligal to be obtained under complex condi.-
tions on traver86s with an average duration of 5 hra. Z Abstrac-

TEXT: The scattering of conduction electrons on spin waves
("ferromagnons") is a contributing factor to the electrical and
thermal conductivity offerromagnetic metals, Owing to its specifi,:
temperature dependence, this part of the conductivity may, under
certain conditions, exceed the conductivity associated with
scattering on phonons. This problem was considered by the second V
of the present authors in Ref.3, where it was shown that the
temperature dependence of the ferromagnon part of electrical
resistivity PT can be written down in the form of two terms,

TEXT: The author proposes a new method for the complete deter-
mination of the three-dimensional state of stress in frozen
slices of a photoelastic model. In his preceding paper (Ref-7)
the author has shown that a normal and two oblique transillumi-
nations of a slice with simultaneous determination of the phase
difference are sufficient to determine five independent compo-
nents of the stress. Now he useB the formulas obtained in (Ref-7)
for the complete determination of the state of stress. Besides
the application of the usual polariscope the author considers
the application of the general method of Ye. S. Fedorov. By an
example the accuracy of the method proposed is verified. The
author thinks that he can conclude that his method be very
effective for the complete determination of the state of stress.

On the Complete Determination of the Three-dimensional State
of Stress by Photoelastic Methods
An advantage of the method is the possibility of an independent
determination of the state of stress in every point. For the
determination of the stresses in a plane only one slice must be
investigated. The absolut phase differences need only be measu-
red for a normal transillumination of the slice.
The proposal of measuring the phase differences is due to B. M.
Zuyev (Ref.11) who constructed a special interferometer for this
purpose.

ABSTRACT: The method of oblique incidence represents one of the
most effective means of separation of principal
stresses when examining the state of plane stresses
by the method of photoelasticity. In case of a three-
dimensional stress this method permits to determine
the tangential stresses and differences in the normal
stresses.. The article systematically expounds the me-
thod of oblique incidence. Formulas for general and

The Application of the Method of Oblique Incidence in Photoelasti-
city
is assumed that by oblique incidence retardation va-
lues as well as parameters of isoclinics are deter-
mined. In addition to the use of common polaris-
cope the application of the universal method of Fe-
dorov is examined. The author also deals with the
problem of determining data for the numerical inte-
gration of equilibrium equations. For the plane
state of stress an analysis of the errors of various
oblique incidence methods is presented (Table 2).
It is shown that in this case the formulas derived
(42) are the most effective. There are _2 t-ables
and 20 references, of which 9 are Soviet, 8 English,
2 French and 1 German.

PERIODICAL: Optika i spektroskopiya, v.14, no.2, 1963, 240-246
TEXT: Various methods.for the determination of phase differences-
with the aid of phase plates are reviewed from the point of view of
the theory of characteristic directions as given by the author in a
previous paper (Izv. AN ESSR, ser.fiz.-mat. i tokhn.nauk,11,1962,
16) " The following methods are considered: 1)'the method of
H.de Se"narmont (Ann.chim.phys.,v-73,1840,337), 2) H.L.Tardy's
method (liev.0pt.,v.8,1929,59)yand 3) the synchronous polariscope
method in which the crossed polarizer and analyzer rotate in
synchronism. A new generalization of de Se'narmont's method is given.
It involves the determination of-the polarizer orientation for which
the light leaving the phase plate in linearly polarized. The method
is similar to that given by H.T.Jessop (Brit.J.Appl.Phys.,v.4,1953,
138). Some useful practical formulas are also given for the
synchronous polariscope method. There is I figure.

ABSTRACT: General equations for the photoclastic method are evolved which are not as
complicated as those in the literature. For example, in publications by V. L. Ginzburg,
the passage of light through an anisotropic nonhomogeneous medium is described by

These equations are the general ones for the photoelastic inethod when light oscillations
are described in fixed coordinates. If we now consider that the quasi-predominant

way, the Neumann equations are obtained. Several Individual cases are considered in
the paper. First, a uniform stressed condition is transformed and solved. 71ten,
quasi-predominant stresses are allowed to change arbitrarily with a fixed direction.
Finally, the uniform rotation of quasi-predominant stresses at a constant value Is
considered and solved. According to R. C. Jones, when polarized light Is passed through
photoclastie models, the components of the light oscillations at the exit point arc linear
functions of the components at the input point. The characteristic direction method for
optical systems Includes integration of a matrix botween the stress components and certain
parameters. For uniform rotation of quasi- predominant directions, numerical solution of
the differential equations yields: CO-3 sp +is.-Isinv
