tWe have prepared different sulfur-overlayers on Cu(001) and Ni(001) surfaces which differ in their cov-erage and local environment of the S adatoms. Via photon absorption we excited the S 2p level andstudied the subsequent Auger decay with a coincidence spectrometer. We discuss the variation of thecoincidence rate as a function of the energy sum of the photo-Auger electron pair. This is linked to thebinding energy of the double-hole state. We find that the photon energy has no dramatic influence on thespectra. Differences are observed when the local environment of sulfur is changed. The observed spectralchanges are mainly ascribable to the variation of the density of states at the different surfaces. On thecontrary, the strength of electron-electron correlation at the surface states is hardly affected by coverageor substrate variation.
