Abstract
A new mode of nuclear fission has been reported, called Collinear Cluster Tripartition
(CCT) which is very rare does not exceed the rate of occurrence of 0.2-
0.4%. The claim is based on indirect observation via missing-energy events,
spontaneous fission of 252Cf. The events were interpreted as perfectly collinear
emission of three heavy fragments. Activities performed in preparation for the
search for ternary fission of heavy nuclei and the analysis of fragment angular
correlations with nuclear track emulsion and an automated microscope are detailed.
Surface irradiation of nuclear emulsion by a Cf source was initiated. Planar events
containing nothing but fragment triples were found and studied.
It is suggested to use a HSP-1000 automated microscope for searching for a
collinear cluster tri-partition of heavy nuclei implanted in NTE, KSM suggested to
use in the measurement some important parameters of every track in the event.
Calibrations of α-particles and ion ranges and energies in a novel NTE are
carried out. Planar events containing fragments and long-range α-particles as well
as fragment triples only are studied. NTE samples are calibrated by ions Kr and Xe
of energy of 1.2 and 3 A MeV.
It has been suggested to use some computer programs to improve the
measurement process to make it easy and save time and effort, such as image J
program for pictures analysis and ROOT graph program.
