摘要:

我们目前的中子热截面,Westcott因子,共振积分,麦克斯韦平均截面和天体物理反应速率的843 ENDF材料使用的数据从主要的评估核库和欧洲激活文件的计算。新评估的中子反应截面,中子协方差和改进的数据处理技术的广泛分析促使我们计算核工业和中子物理量,产生s-过程麦克斯韦平均截面和天体物理反应速率,系统地计算不确定性,并提供额外的见解,目前可用的中子诱导反应数据。讨论了核反应的计算,并给出了新的结果。

英文摘要:

We present calculations of neutron thermal cross sections, Westcott factors, resonance integrals, Maxwellian-averaged cross sections and astrophysical reaction rates for 843 ENDF materials using data from the major evaluated nuclear libraries and European activation file. Extensive analysis of newly-evaluated neutron reaction cross sections, neutron covariances, and improvements in data processing techniques motivated us to calculate nuclear industry and neutron physics quantities, produce s-process Maxwellian-averaged cross sections and astrophysical reaction rates, systematically calculate uncertainties, and provide additional insights on currently available neutron-induced reaction data. Nuclear reaction calculations are discussed and new results are presented.
