摘要

本研究提出了一种新的理论方法来理解核裂变现象和半导体物理之间的统计力学相似性。采用Hill-Wheeler公式作为量子力学分布函数，并与Fermi-Dirac分布函数建立对应关系，利用JENDL-5.0数据分析了9种核素（232Th、233U、235U、238U、237Np、239Pu、240Pu、242Pu、241Am）的核裂变过程。

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

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.

期刊介绍： Entropy (ISSN 1099-4300), an international and interdisciplinary journal of entropy and information studies, publishes reviews, regular research papers and short notes. Our aim is to encourage scientists to publish as much as possible their theoretical and experimental details. There is no restriction on the length of the papers. If there are computation and the experiment, the details must be provided so that the results can be reproduced.
