TEXT: In recent years the authors have -measured the gamma spectra
found in radiative capture of thermal neutrons of numerous elements.
The data obtained are published in a map issued in 1958 and in a
series of articles (Ref. 2). In the article under review, the authors
describe some rules governing the gamma spectra of heavy elements
(A - 100-200) which are not too close to the magic nuclei. This is
illustrated by numerous experimental dicgrams. The spectra of these
elements were taken by means of a magnetic Compton spectrometer
(resolution of 2%) which made it possible to take almost the whole
I-ray spectrum of the (al) zeaction within the range 0.3 - 12 Mev
under the same conditions. The ordinate of the diagrams on the basis

TEXT: This paper was read at the 9th Annual Conference on Nuclear
Spectroscopy. The authors describe an experimental installation at the
reactor of IRT AS'USSR. The installationj which is equipped with a special
magnd-ftc spectrometer, is used for analyzing internal conversion electrons
emitted by nuclei during radiative capture-of thermal neutrons. The
installation is schematically represent6d in Fig6 le Neutrons from the
core of the reactor pass through a channel (diameter# 10 cm) and, after
traveling,4m, incide on the.Cd113 target of the spectrometer. The neutron
beam is 303-3 om large. Inthb-spectrometer, the conversion electrons
coming from the target are focused in opposite direction.to the neutrons
coming from the reactor. The spectrometer contains two magnets of equal

ABSTRACT: The energies of the r -quanta were measured by means of a
scintillation spectrometer. The r-energies can, for com-
pariBOn with other nuclear reaction measurements, be arranged
in level schemes. The following levels (in MeV) were found with

rays In the single spectrum and on coincidence with 725-1 920-1 1030-t
1330-# and 1600-kov rays it is concluded that.the 415-, 725-, 920 -' 1030-,
1330-, and 1600-kov gamma quanta are ir a cascade with the 550- and 630-
key quanta, and that :there occur no transitions to the 550-kev level with
intensities comparable to those of the transitions mentioned above,
except the 630-key transition. The recording of summated spectra (samma-
tion on coincidence) indicated a distinct peak of the aum 630 + 550
1180 key, and, confirmed that the cascade contained 630 and 550-kev
gamma quanta. The coincidence measurements suggest that levels wizh

TEXT: Gd and Od decay scnemes were studied by the method of T 't-coin-,
cidences. The-source used was a Gdl5l, 153 preparation obtained as the decay pro-
duct of Tb151, 153 from a terbium fraction by way.of secondary chromatographic se-
paration (the terbium fraction was ejected from a tantalum target bombarded by
660-Mev protons). The gamma radiation in the 40 - 3~O kev range was recorded by a
coincidence scintillation gamma-ray spectrometer. The resulting energy and gdmma-
,-line intensity values fit data supplied by other authors. The relative intensities
of measured 7 Y-ca6cades are indicated. The absence of strong z-r-coincidences in
t6 Gd151 spectrum is explat-ed. by the existence, in Eu.151, of levels with signi-
ficant lifetime, as is confirmed by the results of lifetime measurements.

ABSTRACT: A method is described for measuring the thickness of steel
artjcl-,~.s with the aid of the registration of diffused radiation
(DR) from a radioactive source of CS137. The variation in the
scintillation y -spectrum in relation to the thickness of the dif-
fuser (D) was studied. 50x5O mm plates located at a distance
of 60 mm from the sc-Antillator were used in the role of D. Also
investigated was the relationship of the intensity of DR and the
thickness a" Al, Fe, and Pb. An elementary estimation of the
latter agrees well with the experimental data. The effect of
the area of D on the measurement of the thickness waB estab-
lished by means of photographing the spectra of DR from cyl-
inders .4-40 mm in diam. It is established that the increase
Card 1/2 in DR is considerably lessened from the 25 mm diam upwards.

SOV/137-58-9-20222
Determination of the Thickness of Steel by Diffused Gamma Radiation
The spectrum of DR was studied in relation to the distance from the D to
the scintillator. On the basis of the data obtained, an instrument was
developed with the aid of which it is possible to measure the thicknesses of
objects approachable from only one side. A block-diagram is given and a
brief description of the operation of the instrqment is ;idduccd.

ABSTRACT: A method is described for measuring the thickness of steel
articles with the aid of the registration of diffused radiation
(DR) from a radioactive source of Csl37. The variat%on in the
scintillation -y -spectrum in relation to the thickness of the dif-
fuser (D) was studied. 50x50 mm plates located at a distance
of 60 mm from the scintillator were used in the role of D. Also
investigated was the relationship of the intensity of DR and the
thickness of A.Ij Fe, and Pb. An elementary estimation of the

The spectrum of DR was studied in relation to the distance frorn thl:- D to
the scintillator. On the basis of the data obtained, an instrument W.;,~s
deveioped with the aid of which it is possible to measure the thicknesses of
objects approachable from only one side. A block-diagram is given and a

ABSTRACT: 1his Author's Certificate introduces: 1. A device for electrical measure-
ment of mechanical quantities using resistance strain gauges. The installation con-
tains a source of stabilized AC voltage, an amplifier and a slide wire with a rever-.
sible electric motor. The unit incorporates three current transformers of the instru-;
ment type to reduce the effect of resistance in the connecting lines 'on measurement re_~
sults. The transformer primaries are connected in series to the source of stabilized
voltage, while thy working strain guage, compensation strain gauge and an adjust le
resistor are connected in the secondary circuits of the first, second and third trans-!
formers res:?ectively either directly or through rectifiers. 2. A modification of this,
device with a fourth current transformer to feed the measurement slide wire.
