ABSTRACTs The degree of apisotropy of the fission of Pu239 was determined
with an ioni2ation chamber. The target of pu239 (with a density of
-300 microgram/GM2) was fastened to a collimator. The fission was
excited by neutrons with -the energy 14,8 MeV. By a simple rotation
of the chamber around it axis 8ne goes over from the counting of
the fragments undeg the :ngle 0 to the counting of the fragments
under the angle 90 (with reference to the neutron beam). The ma-
ximum angle between the digection 8f flying off of ~he fragml~~s
and the fixed direction (0 and 90 ) amounted to 25 . For Pu the
degree of aal6otropy 1,14 was found here. For the degree of aniao-
tropy for U'r-I the value 1,25 was found. Corrections for the motion
of the center of gravity, the inaccuracy of the angle determination
Card 1/2 and for the baeNground of the scattered neutrons were made in the

ly the small number and the low accuracy of the experimental data
do not permit any exacter determination of the dependence of the
degree of anisotropy on the parameters of the nuebus. The quantum
effects may manifest themselves as certain deviations from the fun-
damental tendency for the reduction of the anisotropy on transition
to heavier nuclei. There are 1 figure, and 10 references, 4 of

ABSTRACT: In continuation of a previous paper (RGf 1) the authors of the
present article give further results of investigations of
the anisotropy, carried out by means of a double ioni-zation
chamber. By way of introduction the experimental order is
described (see figure 1) The 14.4 Mev neutrons were foriied
in the reaction T(d,n)He4 - a tritium-zirconium target was
irradiated with 180 kev deuterons. The energy distribution was
determined with respect to two directions 110011 and "900" to
the neutron beam. The neutron source was always at a distance
of 15 cm from the center of the fissioning layer the-diameter of
which was 2.5 cm. The maximum.angle between the direction of
the departure of the fragments and the axis of the collimator
Card 1/3 channel was go; in position 110011 the maximum angle was between

the directions of the neutrons causir43 a fission and of the

angle Was between these two directions ~~750. The energy of
the fission fragments was deterwined by a comparison of the
fragment momenta with the momenta of the a-particles of U258
In each of the two reference directions about 2000 fissions
were recorded. The fraguents may be divided.into 3 groups
according to their proportion by weight; the results of the
measurements of angular distribution are listed in a table:

fragments ratio between the number of

error of +3% with respect to the vertical direction to the
neutron beam. Figure 2 shows the mass.diatribution of the frag-
ments (00, 900) in a diagram. It was found that in the case
of a mass ratio of the fragments smaller than 1.7 - I.B the
angular anisotropy increases with increasing mass asymmetry.
The results were compared with those of other authors and
discussed with respect to the statistical theory of angulax
distribution of fission fragments by V. M. Strutinskiy (Ref 8).
In conclusion, the authors thank M. I. Kuznetsov for assistance.

TITLE: On the Dependence of the Degree of Angular Anisotropy in the

PERIODICAL: Zhurnal eksperimental'noy i teoreticheskoy fiziki 11959,
Vol 36, Nr 5, pp 1573-1574 (USSR)
ABSTRACT: From the recently obtained experimental data on the angular
distribution of the fission fragments of various heavy nuclei
it may be concluded that a certain connection exists between the
degree of anisotropy of the angular distribution 6,(O0]1,q--(qO0)
2
and the parameter Z /A of the fissioned nucleus, for the degree
of anisotropy decreases with increasing Z2/A. The authors of
the present "Letter to the Editor" endeavor to explain this
conneettA theraDdynamically. They base on the assumption that
in the case of a sufficiently high excitation energy of the
compound nucleus the ratio of the fission cross sections at 0
and 960 to the direction of the flight of particles differs
Card 113 considerably from one nucleus to another in accordance with

6,(00)/6~(900)-expr (ALP/T), where AE denotes the difference of the
fission activation energies parallel and perpendicular to the beam,
and T is the temperature of the nucleus in the critical state of
deformation. For the heavy nuclei investigated 4N does not depend
on the structure of the target nucleus and also not on the
properties and the energy of the inoiding particle. Nuclear
temperature before fission depends in a high degree on the
properties of the nucleus (i.e. on Z 2/A) and also on the excitation
