ABSTPACT: It is ometimes necessary, in investigations of nuclear
processes occurring in a layer of a hoto-emulsion, to
determine the angular distribution J particles with res-
pect to a given direction; for this purpose the projection
angle in the observation plane and the angle of tracks
with this plane are usually measured. Under certain
conditions the angular distribution may be established
from the observation of the plane angular distribution
(i.e. by observing the projection). The given distribution
function may be presented by equation 1. Normally the
function n(a) (the observed plane angular track distribu-
tion within the angle a) cannot be analytically derived so
that eventually large errors occur in its numerical
evaluation. The author proposes an.easier method of
evaluating the solid angle distribution from the angular

'ABSTRACT: Nuclear emulsions of 100 and 200 P thickness, which were
saturated with an aqueous solution of NaUO 202H 302)3' were
subjected to the action of a proton beam of 660 MeV. The
fiesioning of the uranium nucleus was connected with the
forming of charged particles. A total of 3201 fissions
(1156 in the thloker emulsion) were recorded. The "beam"-
composition of the fission, i.e. the distribution of the
light, charged partioles produced by the fission, amofinted
to:
0 beams - 43P7 1 beam - 25 '3 %; 2 beams 15,7 %;
5 %; 5 beams

the a-particles and the number of protons was determined
at 0.36 + 0,02.
Besides, the angular distribution of these particles was
measured both with respect to the direction of the 660 MeV
proton beam and to the direction of the fission fragments.
It was found that there is no angular correlation between
the protons and fission fragments. The a-particles and the
multiply charged fission fragments have, quite generally,
the tendency to fly off in the directions which have a large
angle with respect to the fission fragments.
There are 4 figures, 1 table, and 14 references, 10 of which
are Slavic.

TITLE: Cascade oC-Partioles in Nuclear Fission Caused by

ABSTRACT: In their introduction, the authors discuss the results obtained
by several publications dealing with this subject (Refs 1-6).
In the present paper investigations of stars containing tracks
of c4-particles with energies above 30 Mev are described.
The investigations were carried out on photo-plates with a
fine-grained nuclear emulsion P-9 sensitive to protons with
30-40 Mev. The plates vrere subjected to the action of a 360
and 660 Mev proton beam of the Ob"yeainennyy institut yadernykh
iseledovaniy (United Institute for Nuclear Research). Among the
plates with stars containing oL-tracks (EL>30 Ifev) only such
Card 1/4 were chosen for analysis in which the entire m-particle track

was located in the photolayer and in which the track formed
an angle of --70 with the emulsion plane. The star production
cross sections for 360 Mev protons used were taken from the
paper by Bernardini et al. (Ref 9), and those for 660 Mev
protons from that by Grigortyev and Soloviyeva (Ref-10). The
plates investigated were divided into 3 groups; The first
comprised all stars with tracks of a recoil nucleus; they are
assumed to be the result of a disintegration of a heavy emulsion
nucleus (here called T-stars). The second group comprises such
as have no visible tracks of a recoil nucleus (charge carried
away -
