Outline of Final Research Achievements

An electron-spin polarized 4He+ ion beam is useful for analyzing spin of solid surfaces. Deep understanding on spin dependent He+ ion interaction with solid surfaces is indispensable in those analyses. In the present study, systematic investigations of spin-polarized He+ ion scattering spectroscopy have been performed. It was found that spin dependent He+ ion scattering on non-magnetic targets arises from spin-orbit coupling in quantum-mechanical intermediate state during the He+ - target atom binary collision.
