钠原子双激发[2p,3s]→[5s,kl]光电离截面计算

The calculation of photoionization cross section [2p,3s]→[5s,kl] for double excitations of sodium

用多体微扰理论和原子体系图示法 ,研究和讨论了钠原子双激发 [2 p ,3s]→ [5s,kl (ks +kd) ]并计算了钠原子的光电离激发截面 ,计算结果与实验结果相符。

Using Many body perturbation theory and diagrams method, the double electron excitations [2p,3s]→[5s,kl (ks+kd)] have been calculated. Calculated results are in agreement with experiment.
