Abstract

The photon-stimulated desorption (PSD) of O+ ions from the α-oxygen phase on Mo(100) has been monitored through and above the Mo L1(2s) absorption edge (2866 eV) and is compared to the absorption spectrum of clean Mo(100). The PSD ion yield is shown to reveal the extended-x-ray-absorption fine structure of Mo surface atoms which were bonded to oxygen atoms prior to their desorption. Studies of the present kind provide a new powerful tool for surface structure investigations.
