On the origin of high- spin states in nuclear fission fragments

TL;DR

This paper explores the nucleon-phase model of binary fission, explaining high-spin state formation and angular momentum variation in fission fragments through nucleon transfer mechanisms.

Contribution

It introduces a nucleon-phase model that accounts for high-spin states and angular momentum patterns in nuclear fission fragments.

Findings

Nucleon transfer explains high-spin states.

Saw-tooth pattern of angular momentum variation.

Model aligns with observed fission fragment behaviors.

Abstract

In the "nucleon-phase" model of binary fission, the transfer of nucleons between an A =126 {\guillemotleft} nucleon core {\guillemotright} and the primordial "cluster" can explain both the formation of high- spin states and the saw-tooth behavior of the variation, as a function of fragment mass, of the average angular momentum.
