This article describes how to calculate neutron-induced fission reaction cross sections using a proposed empirical formula and the EMPIRE 3.2.3 and TALYS 1.95 computer codes for Uranium isotopes up to the third fission plateau. In this study, the excitation functions of U (n, f), U (n, f), U (n, f), U (n, f), U (n, f), U (n, f) and U (n, f) nuclear reactions were calculated at 1-20 MeV neutron energies. The results were contrasted to measured values from the Experimental Nuclear Reaction Data (EXFOR) as well as the evaluated data from Evaluated Nuclear Data File (ENDF) such as (EAF-2010, JEFF-3.3, ENDF/B-VIII.0 and TENDL-2019). Overall, the calculated, experimental, and evaluated fission cross-sections are in concordance.
本文描述了如何使用一个提议的经验公式以及EMPIRE 3.2.3和TALYS 1.95计算机代码来计算中子诱发的裂变反应截面，该计算针对直至第三个裂变平台的铀同位素。在本研究中，计算了U（n，f）、U（n，f）、U（n，f）、U（n，f）、U（n，f）、U（n，f）和U（n，f）核反应在1 - 20 MeV中子能量下的激发函数。将结果与来自实验核反应数据（EXFOR）的测量值以及来自评价核数据文件（ENDF）的评价数据（如EAF - 2010、JEFF - 3.3、ENDF/B - VIII.0和TENDL - 2019）进行了对比。总体而言，计算得到的、实验测得的和评价得到的裂变截面是一致的。
