论文摘要
复杂的过渡密度可以通过具有复杂基础和/或复杂系数的核结构模型来构建。通常，复杂的跃迁密度转换为具有相位因子的真实一个。在这项研究中，我们将复杂的过渡密度直接应用于微观反应模型。我们与在光学模型的框架，扭曲的波诞生近似和耦合通道（CC）计算中计算的散射横截面进行了比较。此外，我们研究了弹性和非弹性横截面中过渡密度的相位因子的依赖性。在CC计算中可以看到相位因子对弹性和非弹性横截面的影响。最后，我们发现相因在核弹性和非弹性散射中的重要作用。
Complex transition density can be constructed by a nuclear structure model with a complex basis and/or complex coefficient. In general, the complex transition density is converted to the real one with phase factor. In this study, we apply the complex transition density directly to the microscopic reaction model. We compare with scattering cross sections calculated with the real and complex transition densities in the frameworks of the optical model, the distorted wave Born approximation, and the coupled-channel (CC) calculation, respectively. In addition, we investigate the dependence of the phase factor for the transition density in the elastic and inelastic cross sections. The effect of the phase factor on the elastic and inelastic cross sections can be seen in the CC calculation. Finally, we found an important role of the phase factor in the nuclear elastic and inelastic scatterings.
