Abstract
The feasibility of angle reserved;APECS (Auger Photo-Electron Coincidence Spectroscopy) on solids. is demonstrated with an experiment performed at the ALOISA beamline (ELETTRA, Trieste) 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 perform such experiment with goad efficiency. The correlation effects displayed by the measured angular distribution suggest inadequacy of the two step model that is usually adequate far non coincidence experiments performed at the same energy and on the same orbital.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
