ABSTRACT: Transition between the levels of different rotational bands form a dis-
tinctive class and hence are of interest in investigating nuclear structure. The
1095.0 and 913.8 keV transitions accompanying the decay of Lul72 are among the most
intense transitions evinced in the decay of this nucleus and they take place be-
tween the IY( w 3+ level of the K = 3+ band and the 2+ and 4+ levels of the K M 0
rotational band. AI = I (no) allows of Ml and E2 transitions; on the other hand,
change of K by 3 units forbids both types of transitions, although not to the same

calculations are carried out in more detail and the constants entering into the ex-
pressions for the transition probability are re-evaluated. On the basis of these,
certain inferences are drawn regarding the probabilities and multipole orders of
analogous transitions. In the concluding section the concept of "admixture quadru-
pole moments" is introduced and the values of these parameters for Yb172 are evalu-
ated. "We take this opportunity to express our gratitude to A.Meshter, V.A.Balalyev,
L.I.Shalayeva for assistance in the measurements, graduate student of Leningrad Uni-

ABSTRACT- The conversion electron spectrum of 115 day tantalum 182 was investiga-
ted with a double W2' focusing P-spectrometer described elsewhere by one of the au-
thors (S,A.Shestopalova,Izv.AN SSSR,Ser.fiz-25,1302,1961). The measurements were
undertaken in order to record the spectrum at energies above 1220 keV, where It has
not previously been adequately investigated. The source was a tantalum.film vacuum
evaporated onto an aluminum backing. It.wasactivated with thermal neutrons and was
examined four months later. Thirty eight conversion-lines with energies from 822 to
1367 kev were detected and identified; 20 of these had not previously been reporte&

ABSTRACT: This article Is a complete presentation of results from
an experiment reported on earlier In part at th?4gII Congress at
Difona In 1964. A segment of the spectrum of Eu conversion eleo-6
trons was studied In the energy range from 750 to 1550 kav. The ";
article Is primarily made up of graphs and tables representing the.
data from the experiment with a brief description of the setup .1,
and some discussion of the results. It was concluded that a) all-;
the conversion lines observed by other researchers were observed ';
in the present experimenti b) 25 new transitions were disoovered;.
c) all the transitl -on energiesin this range were more preolsely~-
determined. The authors thank Zh. T. Zhelev for his assistance in the receipt of
the sources; L. N. Moskvin for the cleansing of the preparations; and I. F. Uchev.,

ABSTRACT: To verify the electron transitions of Ce135 aving energies of.
187 � 1 and 12.0 �1 kev, a new study was made of the conversion electron spectra:
-ol" the isotope in the electron energy range from 42 to 85. Earlier studies
:had included energies' up ~bo 2660 kev, but since the energy of Ce135 decay
can reach 28000 kev, this study vras eAended from 2660 to 3090 kev. The
.results obtained are compared vrith those of K. Takahashi, et al., J. Phys.
Soc. Japan, Vol. 19, No. 11, p 2014 (1964) in a table, and a systematic
discrepancy is noted: the Japanese energy measurements are consistently
lower- pranging from 0.3 to 2-71%) than those. obtained in this-paper.

Abstract The appearance of horizontal parallel cracks in the top
section of the piers and upstream slope due to severe
frosts (-400C ) on a dam built during the war is
discussed. Causes for this unusual type of weathering
of concrete made of slag portland cement are believed to
be: saturation of concrete with water under pressure,
aided by the solid ice cover which preventathe drying
of Ghe surface, capillary water penetration and the
squeezing out of the air. Research and study of possible
methods of curing and protecting concrete in cold weather
are recommended.

TITLE- Problems Concerning the Thermal Curing of Concrete'. (K voprosu
termoobrabotki betona.)
PERIODICAL: Beton i Zhelezobeton. 1958. No. 1 Pp 19-22.
ABSTRACT: This article carries further the discussion on imprived methods of
steam curing of concrete and reinforced concrete products begun in
this journal 1957 NO- 12. The strength of the products made from
stiff concrete mixes differs considerably from the strength of
products made from more plastic mixes. This is also true if curing
is extended to 4 hours at a temperature of 600. When products are
cured in temperatures above 600C in many cases for 8 hours duration
isotheTmic curing is inexpedient. The same could be said of
temperatures of more than 800 C for a duration of more than four
hours. Tests carried out show that the use of concrete mixes with
a water/cement ratio equal to 0.35 and a duration of isothermic
curing of 6-8 hours for products made from vibro-ground cement
(600 or more) could result in the products having a crushing
strength in compression of 75-64 of testing samples hardening
under norrinal conditions for 28 days. It was considered advisable
that inVis~stigations regarding curing should be intensified to

find out details of increase in the strength of concrete covering
cements of wide mineralogical and chemical compositions. Existing
rccommendations on the curing of concrete are not perfect and need
L
further study. Investigations show that a curing of products made
from concrete mixes with a minimum quantity of water results in a
stronger concrete than products based on mixes with a high water
contcnt. This will be proved in practice and a large saving will
be achieved especially in curing during the winter periods and
large quan-tities of cement will also be saved. Instructions on the

PERIODICAL: Beton i zhelezobeton, 1958, Nr 10, pp -168-372 CUSSR)
ABSTRACT: The new physical and chemical tlieory of -,oncrete put
forward by N,V. Mikhaylov, Dcctor o~' Teohnical S,~iences,
is discussed in this article. It is tased on th-e
assumption that it is possible to obtain 100% activity
from cement used in concrete prapared and cast in this
new way (see also Mikhaylov ix., Be'(-n i zhe-ezobetlon,
19'~8, Nr 9). At the Fourth Sessio._~, of ASiA SSSR
Mikhaylov stressed the significance cf the c-~)n-tent of
calcium aluminate (C3A) in cement. The author of this
article does not agree that investigations into economy
-Ln cement should be confined to the conditions of
crystuallization of C3A , and this view is also
supported in works by V.N. Yung, S.D. Okorokov and
Card 1/4 YU.M. Butt. The presence of belite (C2S) affects the
speed of hardening of cement. An analysis of fifteen-

SOV/97-58-lo-3/17
The Manufacture of Rapid-Hardening7 Durable and Effective Goncretes
for Precast Reinforced Concrete Constructions
year old concrete showed that belite reacts very little
with water. Size of grains of cement has a direct effect
on the process of hardenin This is also proved in a
book by V.N. Yung (Ref 1) fs*ee Fig 1). Tests carried out
by the author of this article with T.Yu. Lyubimova and
F.M. Ivanov In SoyuzdorNII show that in the initial
stages of hardening the presence of belite in cement does
not have any effect on the strength of the concrete.
Table 1 gives values of strength of concrete tested in
compression in relationship to the degree of grinding,
as given in the work of L.D. Yershov (Ref 3).
Investigations carried out by SoyuzdorNII and NIITsement,
with wet grinding of cement showed that in the case of
various types of cement it is possible to add, instead
of clinker, up to 25~% of ground lime. During 1937-40
many tests were carried out in various concreting yards,
including Volgostroy, with so-called 3-component cement.
The results showed that the addition cf finely ground
sand lowers the strength of the concTete. This is also
CaTd 2& desci-ibed in a work by G.M. Rushchulk and L.S. Kogan
(Ref 4). It was shown in works by V.11. Yung and

SOV/97-58-10-3/17

for Precast Reinforced Concrete Constructlons
Yu.M. Butt that the degree of hydratien of portland
cement is hi-her when finely ground mater.-Lal is used for
the cement. Tests carried ou-~ by TsNIIS of MintransstroIr
toget~ier with VNIIstroydormash show that the importariz
factor in the consolidation of stiff concrete mixes is
the equal distribution of amplitude of vibrations along
the whole area of the cast produ~3tj and that the required
frequency of vibration is 3000/7000 per min. Test3
carried out by TsNIIS on consolidation of concrete mi-yes
by double frequency vibrator are described. Fig 2
illustrates the relationship between the strengtl~- of tae
concrete and water/cement ratio, Further tests carried
out by TsNIIS of Mintransstroy show that concrete mixes
with minimal water content have high technical and
economic values, but consolidation by vibration of such
stiff mixes cannot be carried out satisfactorily due to
the inefficiency of the vibrating tables. The
VNIIstroydormash designed and constructed a new type of

ABSTRACT: The authors make the following assumptions: The particles with

high energies (E 0- 10 10 ev) whi--h generate the axtenSi7e
air showers have the absorption range (probeg pcgloshcheriiya)
Labsorption ~ 120 g1cm 2. The 'nteraccior, of the particles with
extremely high energies may be subdividel into two classes:
interactions with low and with high (nearly 100~-) energy losses.
The weak interactions are not take. 1 4n-to account. T~e authors
investigate two simplified schemes of the great energy losses:
a) The whole of the lost energy passes cver to one photon with
the energy E (E denotes the energy of thie pr 4mary n-.-i,-Iea:,-

STUDIES OF LARGE IONIZATION BURSTS BY THE METHOD OF "CONTROLLED PHOTOGPAPHIC

I. Electron-sens-'tive protographic plates were irradiated at 3200 m. above sea
level in a special apparatus, which a recorded large ioniation burst with
the number of particles 1000, and b) indicated through which of the photographic
plates (covering the entire sensitive area of the apparatus) the shower has passed
that produced tle given "burst".
2. The analysis showed that:
(A) the majority of "bursts" are created by showers of electrons generated in
the apparatus by nuclear-active particles of hIgh-energy.
(b) the showers most often consist of one principal "core" apparently created
by a single gamma-quantum of sufficiently high energy;
(c) in cases when the shower contains several laterally separatev "cores"
one of the "core" is, as a rule, responsible for the buld of the
particles in the shower, that is, in the recorded ioniz,tion "burst"
W if in showers that contain two or more "core", the total energy of the
whole shower is taken as unity, the energy distribution of the individual
showers comprising the given shower may be approximated by a power function

T--'XT-. ionization bursts caused by the electron-photon component of a
shower of cosmic-ray particles were studied with an array of ionization
c'-ambers (:ig. 1) at the mountain station (3200 m) of the Akademiya nauk
Armyanskoy SSR (.1cademy of Sciences Armyanskaya SSR). The array consisted
of six rows of ionization chambers separated by layers of lead and
graphite, and covered an area of 10 m2. Owing to this large area, heavy
bursts with a total energy of locally generated X0 mesons &mounting to
~10 13 ev could be photographed. The data obtained were analyzed for

tne nu=;be:, of relativistic particles involved; for each group, the numbers
Of ionization and "Gtructuralized" bursts were determined for rows I-IV.
The spectrum of ionization bursts can be described by N(>!) - Al -Ir for
all chambers. The indox of the integral spectrum for 2-103-_I:!~-2_105
equals 1.37 :: 0.02. 7.4-th an area of ~0.6 M 2 it was found that "20% of the
b-.~rz;ts were "structuralized" for 1-105 1 -~ 5 - 10 3. At I >1-104 and 10 a 2

ture. An analysis of the course of the bursts with the altitude has shown
thatt (1) the integrall spectrum of muon-induced bursts with 3-103 - 3-104
particles has an exponent of 11. 2.22 t 0.14; (2) for a burst Of equal
intensity, induced by a single nuclear-active particle, r - 1.98 t 0.091

2-104 partic es). The burst spectrum was found to depend greatly
on t,-e area of the measuring arrangement. With 2*103 - 2.1o5 particles,

iviLh that of nuclear-active particles, and exhibits no "breaks".
particlez with E >10 12 ev interact with light nuclei in about 10% of the
eventG, the interaction is completely inelastic, and the no energy trans-
fer amounts to 60 - 601;.' of the primary-particle energy. Such interactions
obviously play a significant role in the formation of extensive air
showers with at least 1()4 - 105 particles. There are 8 figures and 7

calculated the particle distribution in showers consisting of 10 , 10
and 10 7 particles as a function of the cascade parameter S. The
calculations were carried out for atmospheric depths of liGoog/cm 2 (sea level)

as determine d byvarious investigators. The present authors studied largd
ionization bursts at an altitude of 3200 m above s.ea level with an arrange-
ment of 92 ionization chambers covering an over4ll area of 10 M2. The,
results showed that a considerable part of the ionizati-on bursts are caused
by nucleqr-active particles falling simultaneously on to the-measuring
apparatus. With a large apparatus the bursts spectrum may be very different
from that of the single nuclear-active particles. This is due to the

TOPIC TAGS: nucleon,- atmosphere, at"anuation length, mu meson, interaction range
.~ISS'TRACT: Iffien a nucleon of high energy interacts with a sifostance, the definite
at-Varnuet-ion length of the nucleon in the substance has an intrinsic value. This
.?aper is devoted to a deter.-tunation of this value in the atmosphere. Computations
show that deeo in the atmos-ohere the attenuation length of nudear-active comoonents
is deterained.only by the absorption of nucleon components. The authors have'used
tl
k1he height behavior of young atmospheric showers for this purpose. Measurements
uere made at heights of 200 and 3250 m. The detecting apparatus had awork;Lng area

it was ~Lound that the frequency of the young showers increased by a factor of 14-16
from sea level to the mountain top. This indicates that LX-mesons play an insig-
njfi*;--~-it role in the formation of young showers. The contribution of kk -mesons
In ovonts at. a height of 3250 m does not p,cceed 1% of the total of the-young
