Abstract Integral cross sections of the reactions 24Mg(n,p)24Na, 27Al(n,p)27Mg, 27Al(n,α)24Na, 58Ni(n,d + np)57Co and 60Ni(n,p)60Co were measured for the first time using the fast neutron spectrum of a TRIGA reactor extending from 0.5 to 20 MeV. The values obtained in this work were comparable with the recommended values for a pure 235U prompt fission spectrum. The measured integral value was utilized for integral test of excitation function of each reaction given in some data libraries, namely ENDF/B-VIII.0, TENDL-2017, IRDFF-1.05 and ROSFOND-2010. The integral measurements are generally consistent with the integrated values within 5 %, except for a few cases, e. g. the reaction 60Ni(n,p)60Co, where the data libraries appear to need improvement.

TRIGA 反应堆快中子引起的几个阈值反应的谱平均截面的积分测量：与各种数据库中给出的激发函数的积分数据进行比较

摘要 测量了反应 24Mg(n,p)24Na、27Al(n,p)27Mg、27Al(n,α)24Na、58Ni(n,d + np)57Co 和 60Ni(n,p)60Co 的积分截面首次使用从 0.5 到 20 MeV 的 TRIGA 反应堆的快中子谱。在这项工作中获得的值与纯 235U 瞬发裂变谱的推荐值相当。测得的积分值用于ENDF/B-VIII.0、TENDL-2017、IRDFF-1.05和ROSFOND-2010数据库中给出的各反应激发函数的积分测试。积分测量值通常与积分值一致，误差在 5% 以内，但少数情况除外，例如。G。反应 60Ni(n,p)60Co，其中数据库似乎需要改进。
