本文介绍了用标准核反应程序TALYS-1.8和EMPIRE-3.2对67，70Zn，92，96,100Mo和208Pb同位素在0-20 MeV能量范围内的(n，p)和(n，2n)反应截面进行模型计算的结果。对程序中提供的不同核能级密度模型和光学模型势进行了检验，以估算所需核反应的截面。此外，本文还详细讨论了复合核过程、预平衡发射和直接反应等不同反应机制对截面的贡献。计算结果与IAEA-EXFOR数据库中现有的实验数据进行了比较。
In this article, we are presenting the results of model calculations for (n,p) and (n,2n) reaction cross sections using the standard nuclear reaction codes TALYS-1.8 and EMPIRE-3.2 for67,70Zn,92,96,100Mo and208Pb isotopes in neutron energy range 0–20 MeV. Different nuclear level density models and optical model potential available in the codes have been tested for the estimation of cross sections of desired nuclear reactions. Moreover, in this work, the contribution to the cross section from different reaction mechanisms such as compound nucleus process, pre-equilibrium emission and direct reaction is also discussed in detail. The calculated results are compared with the existing experimental data from the IAEA-EXFOR database.
