摘　　要：在p+^(60)Ni核反应的理论机制中考虑集体态和转移反应效应,利用大型程序MEND从理论上计算了200 MeV能区内该反应的能谱和6种轻粒子(n、p、α、d、t、~3He)出射的双微分截面。计算结果与实验数据基本一致;与Liang and Cai工作相比,能谱和双微分截面中出现的尖峰的符合更好些。Collective state and transfer reaction are considered. Energy spectra and the double differential cross sections of neutron, proton, alpha, deuteron, triton and helium emissions are calculated for p＋60Ni reaction below 200 MeV with the large calculation code MEND. As a whole, the theoretical results agree with the corresponding experimental data. Compared with the work of Liang and Cai, this paper has a prominent feature in accounting for the peaks of the energy spectra and the double differential cross sections.
