Sažetak
Electron stimulated desorption of negative and positive fluorine ions from BaF2 surfaces has been studied as a function of impact electron energy. Thresholds observed for F1 and F2 are correlated with core-level binding energies of Ba atoms. We propose that core level ionization of Ba ions, followed by an interatomic Auger decay involving halogen ions, can initiate F1 desorption, while the formation and subsequent breakup of superexcited molecular complexes containing a core hole can lead directly to the ejection of negative ions.
