Abstract

Nucleon density distributions and nucleus-nucleus interaction potentials for the reactions $^{16}$O+$^{40}$Ca, $^{16}$O+$^{56}$Fe and $^{16}$O+$^{90}$Zr have been calculated in the framework of the modified Thomas-Fermi method and considering all terms up to the second order in $\hbar$ in the quasi-classical expansion of the kinetic energy. Skyrme forces dependent on the nucleon density are used as the nucleon-nucleon interaction. A parametrization of the nucleus-nucleus interaction potential, which well describes the potential value calculated within the modified Thomas-Fermi approach with density-dependent Skyrme forces, is found. On the basis of the obtained potentials, the cross-sections of elastic scattering are calculated in a good agreement with experimental data.
基于改进的Thomas-Fermi方法的势并考虑核的弹性散射截面
在准经典动能展开中考虑到$\hbar$二阶以下的所有项,在改进的Thomas-Fermi方法框架下计算了$^{16}$O+$^{40}$Ca、$^{16}$O+$^{56}$Fe和$^{16}$O+$^{90}$Zr反应的核子密度分布和核-核相互作用势。依赖于核子密度的Skyrme力被用作核子-核子相互作用。发现了核-核相互作用势的参数化,它很好地描述了在密度依赖的Skyrme力的改进Thomas-Fermi方法中计算的势值。在此基础上,计算了弹性散射截面,与实验数据吻合较好。
