By performing simultaneous detection of forward-scattered Ne ions and photons emitted by Ne and Ni excited atoms when a Ni110 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 on the surface structure on outershell electronic processes during ion-surface collisions.
