论文摘要
我们使用有限范围的简单有效相互作用来构建状态的核方程，以研究核对称能的密度依赖性。 EOSS以核对称能量的良好描述，以$ρ_c= 0.11 $ fm $^{ - 3} $，密度约为饱和密度$ρ_0$的两倍。我们在$^{208} $ pb中获得中子皮肤厚度与散热密度下的密度斜率参数之间的相关性。 A linear relation is obtained between the neutron skin thickness and the parameter $β^{\prime}=\frac{L(ρ_c)}{3E_s(ρ_0)}$, where $E_s(ρ_0)$ and $L(ρ_c)$ are respectively the nuclear symmetry energy at saturation density and the density slope parameter at the subsaturation density.
We use a finite range simple effective interaction to construct nuclear equations of state for the study of the density dependence of the nuclear symmetry energy. The EoSs provide good descriptions of the nuclear symmetry energy at a subsaturation density $ρ_c=0.11$ fm$^{-3}$ and at a density around two times the saturation density $ρ_0$. We obtain a correlation between the neutron skin thickness in $^{208}$Pb and the density slope parameter at the subsaturation density. A linear relation is obtained between the neutron skin thickness and the parameter $β^{\prime}=\frac{L(ρ_c)}{3E_s(ρ_0)}$, where $E_s(ρ_0)$ and $L(ρ_c)$ are respectively the nuclear symmetry energy at saturation density and the density slope parameter at the subsaturation density.
