Abstract
Krypton atoms were excited by photons in the energy range from the threshold for photoionization of the 3d-electrons up to 120 eV, and the fluorescence radiation in the spectral range from 780 to 965 Å was observed and analyzed. Cross sections for the population of excited states in KrIII with at least one 4s-hole resulting from an Auger transition as the first decay step and for KrII satellites were determined. The energy dependence of the 3d-ionization cross section in the 3d-5/2 and the 3d-3/2 threshold range was derived from the experimental data. The cross sections for production of KrII states were found to follow the energy dependence of the 3d-cross sections.
