Abstract The 239Pu(n,γ) cross section has been measured from 10 eV to 1.3 MeV as part of an experimental campaign using the Detector for Advanced Neutron Capture Experiments (DANCE). The work represents a significant advance in experimental technique, with improved systematic uncertainties in key regions in the keV to MeV regime. In general the results of prior work are confirmed with improved uncertainties, particularly at the highest incident neutron energies.

239 Pu(n, γ ) 从 10 eV 到 1.3 MeV

摘要 作为使用高级中子捕获实验检测器 (DANCE) 的实验活动的一部分，239Pu(n,γ) 截面的测量范围为 10 eV 到 1.3 MeV。这项工作代表了实验技术的重大进步，改善了 keV 到 MeV 范围内关键区域的系统不确定性。一般而言，先前工作的结果通过改进的不确定性得到证实，特别是在最高入射中子能量下。
