Krypton 3p excitations and subsequent resonant Auger decay

Krypton 3p excitations and their subsequent resonant Auger decay have been studied. The absolute photoabsorption cross section was determined in the region of the 3p resonances, and some structures were detected in the absorption spectrum. Hartree-Fock calculations including correlation between 3p–1nl and 3d–2n’l’nl configurations were used to interpret the structures of the 3p resonant excitation series and of the corresponding decay spectra. Furthermore, the decay spectra confirmed the assignment of the main structures in the absorption spectrum.
