The close coupling R-matrix method is used to calculate cross-sections for photoionization of Mg III from its first three excited states. Configuration interaction wave functions are used to represent two target states of Mg III retained in the R-matrix expansion. The positions and effective quantum numbers for the Rydberg series converging to the excited state 2s2 2p6 2Se of the residual ion, are predicted. Keywords: Photoionization; configuration interaction; R-matrix method. Pacs Nos. 32.80.-t; 32.80.fb |
