Resonance Auger decay after selective excitation of Kr<i>3d</i>states by synchrotron radiation

Abstract

The ${M}_{4}$,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 3${d}^{9}$4${s}^{2}$4${p}^{6}$5p 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.
