Show affiliationsResonant Auger transitions into 1G4
nl states following Kr 2p3/2 electron excitation have been measured using monochromatized undulator radiation and a hemispherical electron energy analyser. A clear identification of electron peaks was made for 1G4
5s, 1G4
4d, 1G4
5d and so forth when the photon energy approached the ionization threshold. The formation of the 1G4
4d state was found over a relatively wide energy range across the threshold, because of the short lifetime of the 2p hole and of shake effects in electron emission processes. The angular dependence of these decays showed little effect on the polarization direction of the incident photon, which suggests that little anisotropy is related to that of the normal Auger transition into the 1G4 state.
