摘要

在修正的托马斯-费米方法框架内计算了 16O 原子核和 112、114、116、118、120、122、124Sn 同位素的核子分布密度和核-核相互作用势，并考虑了动能的准经典扩展中 ħ 的二阶所有项。依赖于核子密度的 Skyrme 力被用作核子-核子相互作用。对所获得的势进行了成功的参数化，从而能够以分析的形式呈现出来。

The potential of the modified Thomas - Fermi method and its analytical representation on the example of the interaction of 16O with tin isotopes 112,114,116,118,120,122,124Sn

Nucleon distribution densities and nucleus-nucleus interaction potentials for the 16O nucleus and 112,114,116,118,120,122,124Sn isotopes were calculated within the framework of the modified Thomas - Fermi method, taking into account all terms to the second-order of ħ in the quasiclassical expansion of kinetic energy. Skyrme forces dependent on the nucleon density were used as nucleon-nucleon interaction. A successful parameterization was found for the obtained potential, which allows to present it in an analytical form.
