In a recent XUV photoabsorption spectrum of Cs Ⅲ ions by Cummings and O’Sullivan [2001 J. Phys. B 34 199], rather large linewidths were found for the 4d 95s25p6 - 4d 105s25p5 transition which are quite in disagreement with corresponding quasi-relativistic multiconfiguration Hartree-Fock (MCHF) calculation. In the present work, a detailed multiconfiguration Dirac-Fock study has been carried out to explore this discrepancy. Owing to the detailed consid- eration of electron correlation effects, some ’forbidden’ Auger decay channels, such as 4d 105s25p35d and 4d105s05p6, would become ’open’. As a result, remarkable improvement of the linewidths has been obtained in our calculation. Furthermore, the theoretical Auger spectrum of the 4d 95s25p6 core-excited states of Cs Ⅲ ions is given in the present work.
