Variation in resonant Auger yields into the 1G4•nl states of Kr across the L3 threshold
Resonant Auger transitions into 1G4•nl states following Kr 2p3/2 electron excitation have been measured using monochromatized undulator radiation and a hemispherical electron energy analyzer. A clear identification of electron peaks was made for the 1G4•5s, 1G4•4d, 1G4•5d and so forth when the photon energy approached to 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.
