| Outline of Final Research Achievements |
The single spin-rotational state-selected O2 beam enables us to conduct spin and alignment- controlled surface oxidation experiments. But, because of the limitation of its beam energy range and sensitivity, only reactive surfaces were investigated with this method. In this project, the beam energy range was expanded to 0.1-0.9 eV by increasing the number of movable hexapole elements used and implementing the nozzle temperature control. The apparatus has been used for clarifying (1)the origin of the unusual behavior in O2 chemisorption on Pt(111) surface, and (2)the steric effect in Pt steps by utilizing the Pt(553) and (533) surfaces. Another apparatus combining the aligned O2 beam with laboratory XPS machine that allows us to measure the accumulated oxygen during the prolonged O2 beam irradiation was developed for investigating the alignment effect in O2 adsorption on inert surfaces.
