TITLE: Conversion Electrons of Some Neutron-Deficient Ho- and Er-
Isotopes (Konversionnyye elektrony nekotorykh neytrono-
defitsitnykh izotopov Ho i Er )
PERIODICAL: Izvestiya Akademii nauk SSSR, Seriya fizicheakaya, 1958,
Vol. 22, Nr 8, pp. 935 - 940 (USSR)
ABSTRACT: The absence of Tu-lines in the conversion spectra of the
isotopes of the erbium fraction permitted to regard the
sample as being sufficiently pure. Tu was well studied
by Gromov et al.(Ref 7) under similar con~litions- 4 groups
of lines with a half-life of T - 30, 3,5, 2,5-and 1 hours
W
ence concerning the lines
were found. The experimental ev
with T 1/2,~~30 hours (Table 1) well -agrees with the information
furnished by the papers given by references 2 and 3. Hence they
can be ascribed tc the transitions following the decay of
16o
Ho . The investigation of this well studied isotope was
not within the scope of this paper. In spite of a short
irradiation of the tantalum it stood out sufficiently clear
Card 1/3 to permit an identification of the lines. The erbium-isotope

which decays with T 1/2 ~ 3,5 hours was found by Handley
(Khandley and Olson-(Olson)(Ref 5). Mitchel(Mitehel) and
Templeton~Templton)(Ref 8) determined the mass number (A)
of this isotope according to the time of passage through
the mass spectrometer as 161. It can be assumed that the
lines found by the authors which decay with such a hal life
can be ascribed to the transitions of thelgecay of Erif-1
and of his daughter isotope H0161. The Ho 1 with T 1/2 = 2,5
hours is known. Nevertheless this transition cannot be
assigned to this isotope. According to the experimental
conditions the observed half-life should be equal to 3,5
hours (Er16i). Hence the existence of an Er-isotope with
a half-life of 2,5 hours seems to be most probable. A
number of lines was also found which exhib-ited a half-life
of about 1 hour. The investigation of these lines With the
spectrometer at hand met with difficulties. The existence
of 3 lines was reliably determined (Fig 4, Table 8). The
authors expressed their gratitude to X.Ya.Gromov and A.V.

T3XT: After a short introductory discussion of the results obtained by
other authors vhen investigating the 'transition energies of Br16i, the
authors of the present paper give a report on their own results. For
the purpose of explaining the nature of the transition hY = 826 kev
161
of Er , they bombarded tantalum with 660-Mev protons from the synchro-
cjyclot-.ron of the Ob:1yedinenrryy institut yadernykh issledovaniy (Joint
Instituteof Nuclear Research) and investigated the radiation accompanyirg
the erbium decay by m~_ans o7f a scintillation spectrometer and a double
-focusing 0-spectrometer. The half life of this transition was measured
as amounting to (190+10) min, the energy determination gave a value of
(826..5+1.5) kev. For-the purpose of determining the conversion coefficient

of 1;his transition, the electron conversion line ratio and the ratio
of the photopeaks of the gamma s ectrum of this transition and of the
661,,6-kev transition of the BaM nucleus had to be measured. In this
connection it was necessary to take the radiations of the two isotopes
Er 160 and Er1589 which also existed in the preparation, into account; the
greatest correction was furnished by the gamma transitions 648 and 851 kev
of the Ho158_dec4. In an earlier paper, these transitions had already
been investigated and had been identified as E2--transitions between the
second and the first rotational band. The intensity ratio I /I
1826 1848i851
was determined as amounting to 4.0 + 0.2~ If all corrections are taken
into account, a K = 0.008 + 0.002 was obtained for the K.-conversion coeffi-
cient of the 826-kev transition. According to the tables by L,. A. Sliv
and N. I. Band, this gamma transition is of the !ype M1 or E3. In order
to arrive at a decision, the intensity ratio of the conversion lines K/L
was measured and a value 7.0+0-8 was obtained, which excludes the E3.-type.
The intensity ratio of the gamma transitions 211 and 826kAv was measured as

V. M. Dneprovskiy, "on the choice of the intermediate frequency of a superheterodyne
receiver." Scientific Session Devoted to "Radio Day", May 1958, Trudrezervizdat,
Moscow, 9 Sep. 58.
An investigation of the influence of combination components of the mixer current
on the operation of a superheterodyne receiver permits simple expressions which determine
the cho~Lce of the intermediate frequency to be obtained. It is shown that it is possible
to avoid reception on additional channels only f or a limited number of cmbination
frequencies.
A comparative estimate is given of two methods of forming the basic intermediate
frequency signal (fr fs and fr fs) in terms of the degree of the effect of the cCMgi-
nation frequencies on the operation of the superheterodyne receiver.
As particular cases of the analysis, recommendations are given for the choice of
the intermediate frequencies of an unadjusted superheterodyne receiver, an adjusted
superheterodyne receiver with a tuned preselector, a tuned superheterodyne with an untuned
wideband preselector and a superheterodyne receiver with multiple frequency conversion.

TITLEs The Effect of the Combined Current Components of a Mixer on the
Selection of the Intermediate Frequency
PERIODICAL: Radiotekhnika, 1960, Vol. 15, No. 4, pp. 63 - 72
TEXTj In the paper under review, the author describes a universal method used
to analyze'the effect of the combined current components of a mixer on the
selection of the intermediate frequency. A survey of the general conditions is
given in the first part. Equations (100 (11), and (17), (18) are developed,
which permit to estimate the number of superfluous channels by the proper selec-
tion of an intermediate frequency. It is, however, not possible to work out
general recommendations for this purposet but only for each individual type of
mixer and receiver. Crystal mixers have the largest number of combination fre-
quencies. Calculated and experimental data for typical modes of operation of such
mixers are summarized in Table 1. Superheterodyne receivers as well as the de-
mands made on the preselector and the width of the range of intermediate fre-
quencies are studied in great detail. Next, the author describes an improved

superheterodyne with unmodified broad-band preselector. The limits of inter-
mediate frequencies calculated here are summarized in Table 2. On this basis the
author explains how it is possible to avoid superfluous channels. The last part
of the article is devoted to the multiple conversion of frequencies. Two cases
are described in which this frequency conversion is used. In the first case,
good selectivity is intended to be warranted with respect to the mirror and
additional channels, while spectrum analyzers are used in the second case. Ana-
logous conditions for the selection of intermediate frequencies are derived.
There are 3 figuresp 2 tables, and 2 Soviet references.

ABSTRACT: The authors investigated samples of semicodductor single - XyRtpal- mixturps
CdSxcdE;e3.-x, in which the absorption edge can be located in the wavelengtb region
0-5 - 0.7 V, depending on the compositioz~. The samples vere made in the form of
polished bars measuring 8 x 2 x 1-5 mm with contacts deposited on the end faces. The
high resistivity of the samples (P - 101c' ohm-cm) made it possible to produce in the
crystals const" fie44 UP to 3 x 104 V/cm. The shift of the absorption edge for
the crystal C~~6.5=eo.5.. by 30 A. was cbserved at somewhat lower value of the ex-
ternal field and foil-he crystal CdSo.7CdSeo.3, apparently due to the larger slope of
the absorption edge of the sample employed. The results show also that the absorp-
tion coefficient increases in near-parabolic fashion with increasing electric field.
The inertia of the effect will be the subject of further study. The crystals were
grown by Ye. A. Huzalevskiy. Orig. art.bas: 2 figures.

TITLE: Propagation of electromagnetic waves in a plasma

TEXT: The propagation of electromagnetic waves in a direction nor-
mal to the external magnetic field is considered. The existence
and uniqueness of the solution is proved by the method of successi-
ve approximations. Thereuponp integral transforms are used for con-
structing solutions to the problem with initial conditions and the
problem on wave excitation by side currents. Those solutions show
that notwithstanding the presence of complex roots in the correspm-~- V~
ding dispersion equationg no energy transfer takes place from the
plasma to the electromagnetic field (or conversely) during wave-
propagation under steady-state conditions. In the linear approxima-
tion, plane-wave propagation in a plasma is described by equations:

HO is a homogeneous magnetic field, normal to the direction of pro-
pagation. After computations, the problem reduces to two indepen-
dent systems of integro-differential equations in the field compo-
nents. For these two systemst existence- and uniqueness theorems
are proved. The proofs are based on the method of successive appro-
ximations. This method (besides proving the existence and unique"
ness of the solution) permits finding a majoraait estimate for the
solution and to investigate its behavior at the initial stage of
the process. But this method is unsuitable for studying the behavi-
or of the solution at t ---> oo which is of great interest in practi-
ce. This can be achieved by the method of integral transforms whic-

yields explicit expressions for the solutions. Thereby, it is assu-
med that the side currents are harmonic functions of time. The
first system of integro-differential equations is considered; a
Fourier transform (with respect to x) is carried out, and a Laplace
transform (for t); the obtained algebraic system of equations is
solvedp yielding the result:

the Eigenfrequenoies of Electromagnetic
faso.1, 94-97 (1956)
The problem of the modification of these eigenfrequencies in the case of a
slight modification of the shape of the resonator or the introduction of
small, perfectly conductive bodies into the interior of the resonator, was in-
vestigated by many authors by the perturbation method. Because of the compli-
cated nature of the problem all authors were content with the first approxima-
tion, and the problem of higher approximations was not raised. However, for the
problem of the introduction of small conductive bodies into the interior of
the resonator the result obtained by means of the first perturbational approxi-
mation is too rough. On the occasion of attempts made to improve the results of
the perturbation theory for bodies of special shape (sphere, rotation ellipsoid)
the problem regarding the degree of accuracy of the formulae obtained remained
open. The present work investigates the modification of the eigenfreqixencies
of the resonators by the method of successive approximations, on which occasion
convergence is proj~ved first. For the modification of the eigenval, a
general formula is obtained from which results the formula by MAIER and SLATER
for a spherical conductive body.
The general method is also suited for the problem of the modification of eigen-
values as a result of a modification of the parameters E and eL within the re-

sonator. The results obtained in this manner are then compared with the first
approximation of the perturbation theory. It is further shown that, on the
occasion of the introduction of a small dielectric body into the interior of

Theorem: In order that E be an eigenfunction of the problem set here it is
necessary and sufficient that 9 be an eigenfunction of the above mentioned
integral equation.

It follows from this theorem as well as from the aforementioned conditions
that the nucleus Kt is symmetric, integrable-in the square, steady in the
average, and positively definite. Herefrom follows the convergence of the
method of successive approximations for the equation mentioned above. For the
domains of T for which the tensor K t exists there exists a discrete spectrum
of eigenvalues and eigenfunotions of the problem investigated here. The
terms of the functional sequence of the method of the successivo approximations
of the equation mentioned at the beginning satisfies the following relations:

Ennumerical consequences can then be built up for which the recurrence formula
is valid.
It is then presupposed that the volume T is slightly modified either as the re-
sult of a deformation of the external boundary or of the introduction of small
perfectly conductive bodies: T = T + g, where g denotes a small domain with the
boundary 2 + g. --> A --)

modifice,tion of eigenvaluea on the occasion of a modification of the parameters

mentioned because of the introduction of a small dielectric body into a
homogeneous endovibrator, aiid it is specialized for a small sphere.
