论文摘要
在上一篇论文i \ cite {bhagwat20}中，我们表明，与给定有限范围相互作用相关的自洽扩展的thomas-fermi（ETF）势和密度可以通过广义的费米分布来参数化。下一步，使用ETF方案中的Gogny D1S力在本工作中对大量球形和变形的偶数进行了全面计算。纸I的参数化ETF电位和密度用于计算Wigner-Kirkwood半经典平均方案中能量的平滑部分和壳校正。结果表明，因此获得的壳校正以及简单的液态滴剂处方，可以很好地描述跨整个元素周期表的核心的地面质量和势能表面。
In the previous paper I \cite{bhagwat20} we have shown that self-consistent Extended Thomas-Fermi (ETF) potentials and densities associated with a given finite-range interaction can be parametrized by generalized Fermi distributions. As a next step, a comprehensive calculation of ground-state properties of a large number of spherical and deformed even-even nuclei is carried out in the present work using the Gogny D1S force within the ETF scheme. The parametrized ETF potentials and densities of paper I are used to calculate the smooth part of the energy and the shell corrections within the Wigner-Kirkwood semiclassical averaging scheme. It is shown that the shell corrections thus obtained, along with a simple liquid drop prescription, yield a good description of ground-state masses and potential energy surfaces for nuclei spanning the entire periodic table.
