Abstract
Photoexcitation of the Kr 3d to np resonances and photoionization of the 3d inner shell have been studied by measuring the emitted electrons with energies from 0 to 3 eV and from 0 to 12 eV, respectively. Intense discrete structure due to the Kr+ to Kr2+ transitions has been observed in photoelectron spectra. Assignments are proposed based on the spectator shake model and by analysis of effective quantum numbers of proposed Kr+ states. The observed energy shift and asymmetric line broadening, related to the post-collision interaction, of the Kr+ 3d-1(2D512.3) ionic states have been compared with previous experimental results and with theoretical predictions.Keywords
