ENDF/B-VIII.1：面向科学与应用的最新核反应数据库
摘要
ENDF/B-VIII.1 库是由十字线评估工作组 (CSEWG) 推荐的最新评估核数据文件，用于核科学与技术应用，包含自 ENDF/B-VIII.0 发布以来六年间的进展。其中关键进展包括：{^{239}}Pu 文件由国际联合工作重新评估;{^{16,18}}O、{^{19}}F、{^{28-30}}Si、{^{50-54}}Cr、{^{55}}Mn、{^{54,56,57}}Fe、{^{63,65}}Cu、{^{139}}La、{^{233,235,238}}U 和 {^{240,241}}Pu 中子核数据来自 IAEA coordinated INDEN 合作项目;超过 60 个中子剂量测量级联数据来自 IAEA IRDFF-II 库。此外，新库包含针对 {^3}He、{^6}Li、{^9}Be、{^{51}}V、{^{88}}Sr、{^{103}}Rh、{^{140,142}}Ce、Dy、{^{181}}Ta、Pt、{^{206-208}}Pb 和 {^{234,236}}U 中子数据，以及针对光子核、带电粒子和原子子库的新核数据。大量热中子散射核准则被重新评估或首次提供。 在协方差方面，开展了工作以引入更好的不确定性量化标准和测试。重新评估重要核种的大力努力减少了许多积分实验的偏差，特别是针对氟、铜和不锈钢基准的进展尤为突出。数据问题阻碍了前一 ENDF/B-VIII.0 在高熔斷情形下用于商业核能应用的成功部署。通过改进 {^{238}}U 和 {^{239,240,241}}Pu 在共振区的评估数据，已解决这些问题。新库的性能随熔斷程度与参考 ENDF/B-VII.1 库相似。ENDF/B-VIII.1 数据以 ENDF-6 和 GNDS 格式提供，访问地址为 https://doi.org/10.11578/endf/2571019。
