摘要：
The 2s inner shell photoionization (PI) of Na and Auger decay of 1s(2)2s(2)p(6)3s state in Na+ were investigated using single-configuration and multiconfiguration (MC) approximation methods. The PI cross sections from MC calculations showed excellent agreement with experimental and previous theoretical values. The configuration interaction between 1s(2)2s(2)p(6)3s and 1s(2)2s(2)p(6)4s states was essential in predicting PI cross sections. Moreover, configuration interaction played a prominent role in determination of the Auger lifetime widths of Na+ 1s(2)2s(2)p(6)3s (S-1(0)) compared with the experiment.
