EFFECT OF CONFIGURATION INTERACTION ON EXCITATION AUTOIONIZATION CROSS SECTIONS

doi:10.1088/1004-423X/5/10/001

Abstract

Abstract The effect of configuration interaction (CI) on the theoretical calculation of autoionization cross section for Li-like ions are studied in detail by employing the distorted wave Born exchange approximation. We consider the 1s²2s→1s2s2p and 1s²2s→1s2s3p transitions for Cs³⁺ and Al¹⁰⁺ ions. These two transitions account for the largest excitation autoionization cross section. It is found that the CI has a significant effect on the calculated results. The effect becomes larger with increasing atomic number.
