Abstract
The feasibility of angle resolved APECS (Auger Photo-Electron Coincidence S pectroscopy) on solids is demonstrated with an experiment performed at the ALOISA (ELETTRA, Trieste) beamline on the L3M45M45 Auger transition of the Cu(111) surface. This beamline, with its multicoincidence detection system based on several individual electron analysers, was designed in order to pe rform such experiment with good efficiency. The correlation effects displayed by the measured angular distribution are not explained by the two step model, that conversely is commonly accepted f or non coincidence experiments performed at the same energy and on the same orbital.
