抄録

Time-of-flight electron stimulated desorption (TOF-ESD) has been performed to investigate desorption behavior of hydrogen on the surface of V-Ti-Ni alloy. The sample was exposed to hydrogen and oxygen before TOF-ESD measurements. From changes of H<SUP>+</SUP> yields with primary electron energy, the threshold energies of H<SUP>+</SUP> desorptions were estimated to be about 20 eV for hydrogen-exposed sample, and about 16 eV for oxygen-exposed sample. In case of O<SUP>+</SUP> desorption, inflections at the energy-yield curves correspond to Ti 3<I>s</I>, V 3<I>s</I> and Ni 3<I>p</I> binding energies. In contrast, in the relation between H<SUP>+</SUP> yields and primary energy, any inflections were not observed for both hydrogen- and oxygen-exposed samples. In case of 200 L oxygen exposure, both H<SUP>+</SUP> and O<SUP>+</SUP> yields were significantly reduced showing oxidation of the sample.
