Transformations of mass/charges fission fragments spectra with consideration the postfission emission of nuclear particles: 232Th

Abstract

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.
