Abstract
Absolute values for the energies, natural halfwidths and excitation cross sections for the Kr I 3d9np resonances and absolute partial widths for the spectator Auger, participator 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 Kr I 3d9np autoionizing resonances was 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 very simple final-state configuration interaction calculation.
