Photoionization of excited states of neon-like Mg III

摘要

The close coupling e?‘…-matrix method is used to calculate cross-sections for photoionization of Mg III from its ???rst three excited states. Con???guration interaction wave functions are used to represent two target states of Mg III retained in the e?‘…-matrix expansion. The positions and effective quantum numbers for the Rydberg series converging to the excited state 2e?‘?22e?‘?6 2e?‘?e?‘’ of the residual ion, are predicted.
