复跃迁密度在核反应中的应用及相位因子的影响

Application of complex transition density to nuclear reaction and effect of phase factor

备注：: I found a mistake. The sign of the phase depends on the direction of the transition. However, the calculation and formulation in this manuscript do not incorporate that dependence. Since the results and conclusions change, this manuscript is withdrawn

摘要：

复跃迁密度可以通过具有复基和/或复系数的原子核结构模型来构造。一般情况下，复跃迁密度通过相位因子转换为实跃迁密度。在这项研究中，我们将复杂的跃迁密度直接应用到微观反应模型。我们比较了散射截面计算与实际和复杂的过渡密度的框架中的光学模型，扭曲波玻恩近似，耦合通道（CC）计算，分别。此外，我们还研究了弹性和非弹性截面中相变密度与相位因子的关系。在CC计算中可以看到相位因子对弹性和非弹性截面的影响。最后，我们发现了相位因子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.
