Abstract

Abstract: We proposed a new evaluation scheme and standard for the total absorption Gamma ray spectroscopy data of the 70 important short-lived nuclei, combined with direct measurement data for systematic comparison and evaluation, and conducted theoretical research on β decay based on the Gross theory. The research results show the inaccurate description of high-energy density and transition probability caused by odd nucleon is currently the main factor affecting the physics description of decay heat.

Key words: decay heat, fission product, data evaluation, Gross theory
