| Research Abstract |
O2 is a magnetic molecule with an anisotropic shape, and its interaction with surfaces is important technologically. In this study, we prepared a state-selected O2 beam, for which both the spin and the rotational angular momentum are well defined, by using magnetic hexapolar field technique. In O2 sticking on Si(100), we have found that molecules parallel to surfaces are much more reactive than those perpendicular to the surface. We also clarified the dynamical process of O2 adsorption on Al(111), which has been disputed for more than 20 years.
