锂原子激发态(1s^22p)~2P光电离的R-矩阵计算

Calculations in Photoionzation of the Excited State (1s^22p)~2P of Li

文章首次运用R 矩阵理论方法,分别在单通道近似和三态密耦近似下计算了锂原子Li激发态(1s22p)2P的不同过程、不同分波的光电离截面及分波的光电离截面随有效量子数的变化规律。在三态密耦近似下,由于大量的自电离态与连续态的相互作用,计算结果显示了光电离过程中非常丰富的Rydberg系列共振结构,是以前的理论计算中所从未涉及到的。

Using R-matrix method the photoionization cross sections of the excited state (1s^22p)~2P of Li are calculated in the three-state close coupling approximation, and the individual cross section is given.Our calculated results indicate the much Rydberg series of resonance.
