Abstract : The electronic structure of Ti(0001) has been investigated by energy loss spectroscopy (ELS), Auger electron spectroscopy (AES), ultraviolet photoemission spectroscopy (UPS) using synchrotron radiation and electron stimulated desorption (ESD). Resonant electron emission due to a direct recombination process involving an atomic 3p - 3d interaction has been observed. Surface oxidation results in the formation of a thin protective Ti02 layer which is stable to 250 deg C. In the oxide, the direct recombination process following 3p excitation gives rise to resonantly enhanced emission from the oxide valence end. The cross section for electron and photon stimulated O+ desorption is shown to be dominated by these atomic resonance effects as well. (Author)
