Outer-shell electronic processes in Ne⁺ collisions with a Ni(110) surface

By performing simultaneous detection of forward-scattered Ne+ ions and photons emitted by Ne and Ni excited atoms when a Ni(110) surface was bombarded by 4 keV Ne+ ions at near-grazing incidence, we studied the ion and photon yields as a function of the azimuthal angle. The variations observed in the yield anisotropies show the different degrees of influence of the surface structure on outer-shell electronic processes during ion-surface collisions. © 1982.
