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⁺ yields with primary electron energy, the threshold energies of H⁺ desorptions were estimated to be about 20 eV for hydrogen-exposed sample, and about 16 eV for oxygen-exposed sample. In case of O⁺ desorption, inflections at the energy-yield curves correspond to Ti 3s, V 3s and Ni 3p binding energies. In contrast, in the relation between H⁺ 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⁺ and O⁺ yields were significantly reduced showing oxidation of the sample.
