We have carried out calculations for cross sections of ¹⁰²Pd(n,2n)¹⁰¹Pd, ¹¹⁰Pd(n,2n)¹⁰⁹Pd, ¹⁰⁶Cd(n,2n)¹⁰⁵Cd, ¹⁰⁸Cd(n,2n)¹⁰⁷Cd, ¹¹⁰Cd(n,2n)¹⁰⁹Cd, ¹¹⁴Cd(n,2n)¹¹³Cd and ¹¹⁶Cd(n,2n)¹¹⁵Cd reactions via nuclear models which are based on the equilibrium and pre-equilibrium emissions in the interactions of nuclei with neutron particles. The cross sections were determined by means of the model codes EMPIRE 3.2, ALICE/ASH and TALYS 1.8. Besides, the equilibrium and pre-equilibrium effects were performed using Weisskopf-Ewing model, Geometry Dependent Hybrid model, Exciton model and Two-component Exciton model at neutron energies from threshold to 20 MeV. Effects of different level density models on the equilibrium calculations have also been discussed. Furthermore, the empirical systematics, which were suggested in our previous study and in the literature, were used to calculate the (n,2n) cross sections at energies around 14.5 MeV. Thereby, the data obtained were discussed and compared with the measured data in the literature.

我们已经对¹⁰² Pd（n，2n）¹⁰¹ Pd，¹¹⁰ Pd（n，2n）¹⁰⁹ Pd，¹⁰⁶ Cd（n，2n）¹⁰⁵ Cd，¹⁰⁸ Cd（n，2n）¹⁰⁷ Cd，^110的横截面进行了计算Cd（n，2n）¹⁰⁹ Cd，¹¹⁴ Cd（n，2n）¹¹³ Cd和¹¹⁶ Cd（n，2n）¹¹⁵通过核模型的镉反应，该模型基于核与中子粒子相互作用中的平衡和平衡前排放。横截面通过型号代码EMPIRE 3.2，ALICE / ASH和TALYS 1.8确定。此外，在中子能量从阈值到20 MeV时，使用Weisskopf-Ewing模型，几何相关混合模型，激子模型和两组分激子模型进行了平衡和预平衡作用。还讨论了不同水平密度模型对平衡计算的影响。此外，在我们先前的研究和文献中提出的经验系统被用来计算能量在14.5 MeV附近的（n，2n）截面。因此，讨论了获得的数据并将其与文献中的测量数据进行比较。
