摘要
对用单能中子源作活化截面测量时低能中子干扰的影响作了分析研究，并从测量的两种常用中子源T（d，n）4He和D（d，n）3He的中子源能谱中验证了这种定性分析．最后给出了两个比较典型的反应（58）Ni（n，P）（58）Co和（64）Zn（，P）（64）Cu反应的截面测量结果．
The effect to low energy neutrons from monoenergetic neutron source on achvation cross section measurements was analysed and studied. This analysis was proved by the measured neutron spectra of T(d,n)4He and D(d,n)3He neutron sources. Finally the cross sections for (58)Ni(n,p)(58)Co and (64)Zn(n,p)(64)Cu reaction were given.
