The recent observation of neutron stars merger by the laser interferometer gravitational-wave observatory collaboration and the measurements of the event’s electromagnetic spectrum as a function of time for different wavelengths have altered profoundly our understanding of the r-process site as well as considerably energized nuclear astrophysics research efforts. R-process abundances are a key element in r-process simulations, as a successful calculation must account for these abundances in the final debris of a stellar cataclysmic event. In this article, mankind’s complete knowledge of neutron cross sections obtained over the last 80 years, as encapsulated in the latest release of the evaluated nuclear data file (ENDF/B) library, is used to obtain solar system r-process abundances in a comprehensive data approach. ENDF/B cross sections have been successfully used for decades in nuclear power and defense applications and are now used to obtain r-process abundances in a fully traceable and documented way. This article r-process abundances provide complementary insights on the astrophysical events, overall quality of neutron capture data in the astrophysical region of temperatures, and demonstrate issues with the s-process contribution subtraction procedure.

最近通过激光干涉仪引力波天文台合作对中子星合并的观测以及对不同波长的事件电磁波谱的测量，深刻地改变了我们对r 过程站点的理解，并极大地激发了核天体物理学。研究努力。R-过程丰度是r的关键元素- 过程模拟，因为成功的计算必须考虑到恒星灾难性事件的最终碎片中的这些丰度。在本文中，人类在过去 80 年中获得的中子截面的完整知识，封装在最新版本的评估核数据文件 (ENDF/B) 库中，用于全面获取太阳系r 过程丰度数据方法。ENDF/B 横截面已在核电和国防应用中成功使用了数十年，现在用于以完全可追溯和记录的方式获取r 过程丰度。本文[R过程丰度提供了对天体物理事件、天体物理温度区域中中子捕获数据的整体质量的补充见解，并演示了s过程贡献减法程序的问题。
