标题： Spectroscopic amplitudes and microscopic substructure effects in nucleon capture reactions

摘要： 光谱振幅在核捕获反应中起着重要作用。 这些振幅包括单粒子效应和极化效应：前者通过它们的空间依赖性，后者通过它们的归一化（光谱因子）。 为光谱振幅建立了耦合通道方程。 这些方程作为推导几种近似的便利起点： 哈特里近似、哈特里-福克近似和两种不同的单粒子模型。 单粒子模型以不同的方式包含反对称性，但都忽略了许多体效应。 因此，使用这些模型计算的截面需要乘以光谱因子。 显示英文摘要

摘要： Spectroscopic amplitudes play an important role in nuclear capture reactions. These amplitudes are shown to include both single-particle and polarization effects: the former through their spatial dependence and the latter through their normalization (the spectroscopic factors). Coupled-channels equations are developed for the spectroscopic amplitudes. These equations serve as a convenient starting point for the derivation of several approximations: Hartree, Hartree-Fock and two different single-particle models. The single-particle models include antisymmetry in different ways, but both miss many-body effects. Therefore, cross sections calculated with either of these models need to be multiplied by the spectroscopic factor.
