论文摘要
不对称半无限核物质的中子皮肤厚度被证明是库仑能量的函数，不对称能量的不对称能量系数（$ j $），不对称能量的坡度（$ l $），以及不可压缩性系数，除了他的fermi Momennum MomkiMMoment和不对称的参数外。关系公式根据核物质平均场近似中的Hugenholtz-Van Hove定理得出。使用该公式作为指南，检查了$^{208} $ pb中的中子皮肤厚度（$ΔR$）。 $ L $和$ΔR$之间的线性相关性通过$ L $与$ J $的模型相关性与$ j $的模型相关性作为一种虚假的相关性，该相关性包含在公式的主要组件中。
The neutron-skin thickness of asymmetric semi-infinite nuclear matter is shown to be a function of Coulomb energy, the asymmetry-energy coefficient($J$), the slope($L$) of the asymmetry energy, and the incompressibility coefficient, in addition to he Fermi momentum and the asymmetry parameter. The relational formula is derived on the basis of the Hugenholtz-Van Hove theorem in the mean-field approximation for nuclear matter. Using the formula as a guide, the neutron-skin thickness($δR$) in $^{208}$Pb is examined. The linear correlation between $L$ and $δR$ appears as a kind of spurious ones through the model-dependent correlation of $L$ with $J$ which is included in the main components of the formula.
