| Outline of Final Research Achievements |
The single spin-rotational state-selected O2 beam allows us to conduct spin- and alignment-controlled surface oxidation experiments. The equipments necessary for monitoring the spin effect in O2 chemisorption, the alignment effects in O2 scattering and catalytic oxidation reaction were developed in this project. (1)The O2 chemisorption probability on a magnetized Ni surface was found to depend on the mutual spin orientation. (2)Clear alignment effects were found in the angular distribution of O2 scattered from HOPG and LiF(100) surfaces. This can be understood based on the effective surface roughness, which depends on the O2 geometry relative to the surface. (3)The CO oxidation reaction on Pt(111) was found to proceed only when O2 axis is nearly parallel to the surface if the translational energy of O2 is < 0.2 eV.
