Mg 3p_jnd_(j') (j = 1,3) autoionizing series

摘要

The spectroscopic properties of Mg 3pnd (j = 1, 3) autoionizing states have been studied by employing the combination of multichannel quantum defect theory with the R-matrix method. Energy levels of the 3pnd (j = 1) autoionizing states are obtained with resolution of fine-structure splitting. The transition lineshapes of the 3pnd (j = 3) are calculated using a theoretical model with the more complete channels. The possible impact of the higher angular momentum states on the Mg 3pnd (j = 3) autoionization spectra have been investigated. The results presented agree well with recent experimental and theoretical studies.
