摘　　要：以现有p+60Ni核反应的实验数据为基础,利用自行研制的大型程序MEND从理论上系统地计算了200MeV能区内p+60Ni核反应的反应截面、弹性散射角分布、能谱和6种轻粒子(n、p、α、d、t3、He)出射的双微分截面.与实验数据及ENDF/B6评价库比较发现,文章理论计算的结果与实验数据基本一致;与ENDF/B6相比,文章增加了3He的计算,将能区上推到了200 MeV,结果更接近实验数据、更全面.Based on the experimental data of p＋^60 Ni reaction,all kinds of reaction cross sections, elastic scattering angular distributions,energy spectra, and the double differential cross sections of neutron, proton,alpha,deuteron, triton and helium emissions were calculated for p＋^60 Ni reaction below 200 MeV with MEND which was a large calculation code developed by ourselves. The theoretical results were compared with the existing experimental data and with the results of ENDF/B6 evaluation file. As a whole,the theoretical results agreed with the experimental data. Compared with ENDF/B6 file,the calculations of 3 He emission were considered and the energy region was up to 200 MeV in this paper. Our results were better and more detailed.
