Resonance Auger decay after selective excitation of Kr3dstates by synchrotron radiation

Abstract
The M4,5NN normal and resonance Auger spectra of Kr have been measured using different photon energies to ionize or excite the 3d levels. Excitation of the 3d electrons to the 3d94s24p65p resonance states results in decay with a 5p spectator or participator electron. The spectra are analyzed by comparing them with the calculated profiles. The calculations take into account the presence of a spectator electron, and the correlation effects in the case of a 4s hole state.
