我们提出了第一个系统的非局域色散光学模型分析使用的束缚态和散射数据，和。在所有系统中，大约一半的总核结合能与总核子密度的最束缚10%有关。所提取的中子皮肤揭示了不对称性，库仑，壳效应的皮肤厚度的相互作用。我们的研究结果表明，同时光学模型拟合的非弹性散射和同位素对的结构数据是有效的约束非对称依赖的核结构量，否则难以观察实验。
We present the first systematic nonlocal dispersive optical model analysis using both bound-state and scattering data of,,,, and. 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.
