Abstract
Absolute values for the natural halfwidths and excitation cross sections for the KrI 3d9np resonances and absolute partial widths for the spectator Auger and Auger shake decays of the Kr I 3d5/295p and the Kr I 3d5/295p resonances into Kr II states have been collected and critically discussed or have been extracted from already published relative literature data. By means of photon-induced fluorescence spectroscopy a cascade population of the Kr II 4s14p6 2S1/2 state following the excitation of the KrI 3d9np autoionizing resonances has been observed and quantified. It is ascribed to a cascade process involving a correlative radiative transition of the type 4s24p45p 2S+1LJ → 4s14p6 2S1/2 within Kr II. The probability of this process is explained within a simple final-state configuration interaction estimation.
