Abstract We present details of the prompt fission gamma property evaluations included in the released ENDF/B-VIII.0 files. The average prompt gamma multiplicity, the average prompt gamma spectrum, the average total prompt gamma energy released and the prompt gamma multiplicity distributions, included in the ENDF/B-VIII.0 files, are presented for 235U(n,f), 238U(n,f), and 239Pu(n,f) reactions, as a function of incident neutron energy up to 30 MeV. The evaluation is based on available experimental data and model calculations. Notable data include recent measurements by experimental groups at Los Alamos and Lawrence Livermore National Laboratories, at Geel and Budapest, at CEA labs, as well as seminal historical gamma production measurements by Drake at Los Alamos.

对 235,238U 和 239Pu 中子诱导裂变的快速裂变伽玛特性的评估

摘要 我们提供了包含在已发布的 ENDF/B-VIII.0 文件中的即时裂变伽马特性评估的详细信息。ENDF/B-VIII.0 文件中包含的平均瞬发伽马多重性、平均瞬发伽马谱、释放的平均总瞬发伽马能量和瞬发伽马多重性分布分别针对 235U(n,f)、238U( n,f) 和 239Pu(n,f) 反应，作为高达 30 MeV 的入射中子能量的函数。评估基于可用的实验数据和模型计算。值得注意的数据包括洛斯阿拉莫斯和劳伦斯利弗莫尔国家实验室、吉尔和布达佩斯、CEA 实验室的实验小组最近进行的测量，以及德雷克在洛斯阿拉莫斯进行的开创性历史伽马生产测量。
