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

## TL;DR

This paper introduces a statistical approach to analyze how post-fission emission of particles like neutrons and beta particles affects the mass and charge distributions of fission fragments, using 232Th as a case study.

## Contribution

It presents a novel method for examining the impact of emitted nuclear particles on fission fragment yields and their topological changes, improving interpretation of experimental data.

## Key findings

- Identifies the most probable fission fragment clusters considering particle emission.
- Shows the influence of particle emission on symmetric and asymmetric fission modes.
- Provides insights into the stability parameters of fission fragments.

## 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.
