Resonant Auger spectrum following Kr : 2p -> 5s photoexcitation

Resonant Auger electron spectra following Kr:2p --> 5s photoexcitation have been measured for the first time using monochromatized undulator radiation and a cylindrical minor electron energy analyser. It is found that the kin etic energy of the resonant Auger electron is higher than that of the corre sponding normal Auger electron. The angular distribution of the resonant Au ger electrons is nearly isotropic relative to the polarization direction of the incident light.
