论文摘要
我们介绍了使用$^{16,18} $ O，$^{40,48} $ CA，$^{58,64} $ ni，$^{112,124} $ SN，以及$^{208} $ pb的第一个系统的非局部非局部分散光学模型分析。在所有系统中，总核结合能大约与总核密度最大的10％有关。提取的中子皮肤揭示了不对称，库仑和壳对皮肤厚度的影响的相互作用。我们的结果表明，同位散射和同位素对上的结构数据的同时拟合了对限制不对称依赖性核结构量的有效性，否则很难通过实验观察到。
We present the first systematic nonlocal dispersive optical model analysis using both bound-state and scattering data of $^{16,18}$O, $^{40,48}$Ca, $^{58,64}$Ni, $^{112,124}$Sn, and $^{208}$Pb. In all systems, roughly half the total nuclear binding energy is associated with the most-bound 10% of the total nucleon density. The extracted neutron skins reveal the interplay of asymmetry, Coulomb, and shell effects on the skin thickness. Our results indicate that simultaneous optical model fits of inelastic scattering and structural data on isotopic pairs are effective for constraining asymmetry-dependent nuclear structural quantities otherwise difficult to observe experimentally.
