非对称核弯曲界面效应的Gibbs-Tolman方法
Gibbs-Tolman approach to the curved interface effects in asymmetric nuclei
摘要：
本文重新定义了具有有限扩散层的非对称核费米液滴的表面张力系数和对称能。考虑两组分荷电费米液滴，遵循Gibbs-Tolman概念，引入了表面张力作用下尖锐液滴的等摩尔半径$R_{e}$和表面张力系数$σ$最小的张力面半径$R_{s}$（Laplace半径）。我们证明了核Tolman长度$ξ$是负的，并且$ξ$的生长模量与不对称参数$X=(N-Z)/(N+Z)$成二次关系。
英文摘要：
We redefine the surface tension coefficient and the symmetry energy for an asymmetric nuclear Fermi-liquid drop with a finite diffuse layer. Considering two-component charged Fermi-liquid drop and following Gibbs-Tolman concept, we introduce the equimolar radius $R_{e}$ of sharp surface droplet at which the surface tension is applied and the radius of tension surface $R_{s}$ (Laplace radius) which provides the minimum of the surface tension coefficient $σ$. We have shown that the nuclear Tolman length $ξ$ is negative and the modulus of $ξ$ growth quadratically with asymmetry parameter $X=(N-Z)/(N+Z)$.
