Shake processes of different origin are identified in the KLL Auger spectrum of H2S with unprecedented detail. The KLL Auger spectrum is presented together with the S 1s(-1) photoelectron spectrum including the S 1s(-1)V(-1)n lambda and S 1s(-1)2p(-1)n lambda shake-up satellites with V-1 and n lambda indicating a hole in the valence shell and an unoccupied molecular orbital, respectively. By using different photon energies between 2476 and 4150 eV to record the KLL Auger spectra two different shake-up processes responsible for the satellite lines are identified. The first process is a shake-up during the Auger decay of the S 1s(-1) core hole and can be described by S 1s(-1) -> 2p(-2)V(-1)n lambda. The second process is the Auger decay of the shake-up satellite in the ionization process leading to S 1s(-1)V(-1)n lambda -> 2p(-2)V(-1)n lambda. transitions. By combining the results of photoelectron and Auger spectra the involved V(-1)n lambda levels are assigned.
