Application of the Hill-Wheeler Formula in Statistical Models of Nuclear Fission: A Statistical-Mechanical Approach Based on Similarities with Semiconductor Physics.

Abstract

This study proposes a novel theoretical approach to understanding the statistical-mechanical similarities between nuclear fission phenomena and semiconductor physics. Using the Hill-Wheeler formula as a quantum mechanical distribution function and establishing its correspondence with the Fermi-Dirac distribution function, we analyzed nuclear fission processes for nine nuclides (²³²Th, ²³³U, ²³⁵U, ²³⁸U, ²³⁷Np, ²³⁹Pu, ²⁴⁰Pu, ²⁴²Pu, ²⁴¹Am) using JENDL-5.0 data.
