考虑到自1979年以来发表的所有已知的相关数据，重新评估了原子序数为1至83的元素和同位素（以及Th和U）的热辐射俘获截面和共振积分。这项工作是作为原子能机构协调的“即时捕获伽马射线活化分析”研究项目的一部分进行的。利用INTER程序和ENDF-B/VI（Release 8）库文件计算了300 K温度下辐射俘获截面的Westcott g因子。在150、294和400 K的温度下，示出了Cd、Nd和Gd的Westcott g因子的温度依赖性。新评估的捕获截面的Li，Li，C和Pb的k 0方法所确定的那些也进行了比较。
The thermal radiative capture cross sections and resonance integrals of elements and isotopes with atomic numbers from 1 to 83 (as well as Th and U) have been re-evaluated by taking into consideration all known pertinent data published since 1979. This work has been undertaken as part of an IAEA co-ordinated research project on "Prompt capture gamma-ray activation analysis". Westcott g-factors for radiative capture cross sections at a temperature of 300K were computed by utilizing the INTER code and ENDF-B/VI (Release 8) library files. The temperature dependence of the Westcott g-factor is illustrated for Cd , Xe and Gd at temperatures of 150, 294 and 400K. Comparisons have also been made of the newly evaluated capture cross sections of Li, Li, C and Pb with those determined by the k0 method.
