Findings

Explains the ordering of U, Pa, Th, Ac, Ra fission fragments.

Calculates neutron emission functions using the new method.

Demonstrates the method's ability to analyze post-fission fragment spectra.

Abstract

A new statistical method for systematizing the nuclei fission fragments, investigation of their mass and charge spectra and neutron fission parameters has been suggested. In proposed method, the mass and charge yields of nucleons are determined from the equilibrium conditions of the nuclear fragments post-fission ensemble. Here we consider protons and neutrons of different fragments as statistically non-equivalent. The abilities of the proposed statistical method for explanation of the U, Pa, Th, Ac and Ra post-fission fragments ordering and neutron emission function calculation have been demonstrated.
