本工作调研了中子俘获辐射截面系统学国际上的研究现状。国际上关于俘获辐射截面的系统学研究主要包括单能点截面(热能点、14MeV附近和30keV附近平均截面)、激发函数以及能谱的研究。收集了裂变核在热能点的中子俘获辐射截面实验数据,调研了包括ENDF/B-Ⅶ.0的382个核素、JENDL-4.0的398个核素和CENDL-3.1的232个核素和BNL实验室的评价数据,在此基础上
This work investigates the current international research status of neutron capture radiation cross-section systems. Systematic studies on the capture of radiation cross sections in the world mainly include the study of single energy point cross sections (thermal energy points, 14MeV near the 30keV average cross section), excitation function and energy spectrum. The experimental data of neutron capture radiation cross section of fission nuclei at the thermal energy point were collected. 382 nuclides including ENDF / B-Ⅶ.0, 398 nuclides of JENDL-4.0 and 232 nuclides of CENDL-3.1 were investigated. BNL laboratory evaluation data, based on this
