  The possibilities of the proposed statistical approach are shown in the task
of investigating the post-scission transformation of mass and charge yields of
fission fragments with considering the emission of different length of chains
of elementary particles as the beta particles and neutrons fission. Using as
the example the 232 Th isotope, which is located on the border between
pre-actinide and actinides nuclei, the changes in the topology of fission
fragments yields, the role of emission of nuclear particles in the competition
of symmetric and asymmetric modes in fission processes are investigated. The
proposed method allows one to determine the most probable two fission's
fragments clusters, obtained in considering the different chain's length of
emitted nuclear particles and the parameters of their stability. All these
results are essential when interpreting the experimental data.
