Abstract
The photon-stimulated desorption (PSD) of ions from the -oxygen (high-coverage) phase on Mo(100) has been studied using synchrotron radiation in the spectral range 17-570 eV. The ions were detected and mass analyzed by means of time-of-flight spectroscopy. The yield shows resonances at all Mo core levels and the level of oxygen. The results are discussed in terms of inter- and intra-atomic Auger transitions following the primary core excitation. The applicability of PSD as a probe for surface extended x-ray absorption fine-structure measurements is discussed.
