本文综述了非局域色散光学模型（DOM）在核结构和核反应同时描述中的应用。40 Ca和48 Ca的所得电位的质量的评估进行了讨论的描述的（E，E'P）反应的价空穴状态和解释的数据在绝对光谱因子的可能性。这些结果的相关性的背景下，相互冲突的解释之间的转移和敲除反应指出，以及质子反应截面的重要性与中子过剩的同位素。将非局域DOM应用于48 Ca结合了8个额外中子的影响，并可以很好地描述质子和中子的弹性散射数据。相应的中子分布约束所有可用的数据生成的预测是大于大多数平均场和可用的从头算结果的中子皮肤。结果是最近的非本地DOM分析208铅。
A review of recent applications of the nonlocal dispersive optical model (DOM) is presented that allows a simultaneous description of nuclear structure and nuclear reactions. An assessment of the quality of the resulting potentials for 40 Ca and 48 Ca is discussed for the description of the (e, e'p) reaction to valence hole states and the possibility of interpreting the data in terms of absolute spectroscopic factors. The relevance of these results in the context of conflicting interpretations between transfer and knockout reactions is pointed out as well as the importance of proton reaction cross sections for isotopes with neutron excess. Application of the nonlocal DOM to 48 Ca incorporates the effect of the 8 additional neutrons and allows for an excellent description of elastic scattering data of both protons and neutrons. The corresponding neutron distribution constrained by all available data generates a prediction for the neutron skin that is larger than most mean-field and available ab initio results. Results are presented for the most recent nonlocal DOM analysis of 208 Pb.
