摘要: 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Li原子激发态 (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. 计算结果表明, 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, 光电离过程中存在非常丰富的 Rydberg 系列共振结构.

Abstract: The present paper covers the photoionization sections o f the different processes and different partial waves of the excited state(1s 22p)2P of Li calculated by means of R-matrix method in the single channe l approximation and the three-state close coupling approximation, and the regul arity of the photoionization sections of the partial waves with the effective qu antum number. The results show that in the three-state close coupling approxima tion, there exists a wealth of Rydberg series of resonance structures in the pro cedure of pho-toionization due to the interaction between the autoionization st ate and the continuation states.

Key words: photoionzation, R-matrix method, three-state close ap proximation, autoionization state, rydberg resonance
