Abstract 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 ${\rm 4d}^{\,9} {\rm 5s}^2 {\rm 5p}^6 \,- \,{\rm 4d}^{\,10} {\rm 5s}^2 {\rm 5p}^5$ 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 consideration of electron correlation effects, some 'forbidden' Auger decay channels, such as ${\rm 4d}^{\,10} {\rm 5s}^2 {\rm 5p}^3 {\rm 5d} $ and ${\rm 4d}^{\,10} {\rm 5s}^0 {\rm 5p}^6 $, would become `open'. As a result, remarkable improvement of the linewidths has been obtained in our calculation. Furthermore, the theoretical Auger spectrum of the ${\rm 4d}^{\,9} {\rm 5s}^2 {\rm 5p}^6$ core-excited states of Cs III ions is given in the present work.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
