摘要
使用R-矩阵方法,采用三态密耦图象计算了锂原子激发态1s2p2P的光电离截面,并给出了不同分波及不同过程的截面。计算结果揭示了光电离过程中的Rydberg系列共振,并指出在非共振区光电离截面不是单调变化的。
Using R-matrix method the photoionization cross sections of atomic lithium were calculated in the three state close coupling approximation, and the partial cross sections and the individual cross sections were given. Our calculated results indicate the Rydberg series of resonance, and non-monotone change of photoionization cross section in the non-resonance region.
