Abstract

The valence photoionization and resonant Auger decay at 4d resonances below the 4d ionization threshold in Sb-4 clusters have been studied experimentally by means of photoelectron spectroscopy. The 4d absorption spectrum in the photon energy region from 30 to 36 eV has been recorded using the constant ionic state (CIS) partial electron yield (PEY), and the CIS spectra for various ionic states are presented. The photoelectron spectra at various resonant positions are recorded, and the results and their interpretation are presented. The findings provide experimental proof of the previous assignment of the various structures of the inner valence photoelectron spectrum.
