Non-Statistical gamma Rays from Fragments

TL;DR

This paper investigates a non-statistical mechanism for gamma-ray emission from nuclear fragments, focusing on electric dipole radiation caused by deformation energy during the fission process, with a calculated probability of about 3.5%.

Contribution

It introduces a polarization mechanism based on Strutinsky-Denisov effects that explains gamma-ray emission during nuclear fission, providing quantitative probability estimates.

Findings

Gamma-ray emission probability is approximately 3.5% per fission.

Emission occurs during thermolization before neutron emission.

Electric dipole radiation is driven by post-rupture deformation energy.

Abstract

Polarization mechanism by Strutinsky-Denisov gives rise to the electric dipole radiation from fragments. Its probability calculated within the LDM turns out to be ~3.5x10-2 per fission. The radiation occurs during thermolization of the post-rupture deformation energy of the fragments, but before the neutron emission.
