摘要
基于多组态Dirac-Fock方法,理论研究了钠原子2p光电离过程高分辨率的光电子谱及振激跃迁过程的相应伴线谱。展示并解释了正常光电离和强振激跃迁过程相应光电子谱的主要特征;结果表明光电离后2p空穴的电子关联在一定程度上改变了相应谱线的能量位置,对出射光电子谱的结构有很大影响。实验测量与理论模拟谱之间的一致性说明了该理论方法的可靠性,从而能够正确辨认相应的实验观测谱线。
Based on multiconfiguration Dirac-Fock method,the high-resolution 2p photoelectron spectra and satellites originating from the corresponding shakeup transitions during the photoionization of neutral sodium atoms are theoretically studied.The main features of photoelectron spectra from the normal photoionization and strong shake-up transitions are presented and interpreted.It is shown that the electron correlations of the 2p hole affect the energy positions of photolines and give rise to considerable structures in the photoelectron spectra.The reasonable agreement between the measured results and simulated spectra confirms the reliability of the theoretical approaches and enables us to assign the observed photolines.
