The nucleus-nucleus interaction potentials for the ${}^{16}\mathrm{O}+{}^{58,60,62,64}\mathrm{Ni}$ systems are calculated within the extended Thomas-Fermi method by taking into account all terms up to terms of the second order in ħ of the quasiclassical decomposition of kinetic energy. The density-dependent Skyrme force is used as the nucleon-nucleon interactions. Using the obtained potentials, the cross sections of subbarrier fusion and elastic scattering are found, which are in good agreement with the experimental data.

扩展的Thomas-Fermi方法内的核-核势以及系统¹⁶ O +  ^58,60,62,64 Ni的亚^势垒融合和弹性散射的横截面

核的核-核相互作用势 ${}^{16}\mathrm{Ø}+{}^{58，60，62，64}\mathrm{你}$在扩展的Thomas-Fermi方法中，通过考虑动能的准经典分解的ħ中的所有项，直至二阶项，来计算系统。依赖于密度的Skyrme力被用作核子-核子相互作用。利用获得的电势，发现了亚壁垒融合和弹性散射的横截面，与实验数据非常吻合。
