Abstract
We measured the fine structure of the Cu L(3)M(4,5)M(4,5) Auger line e xcited by impact of MeV protons upon a Cu(110) surface, In case of a g razing incidence, a shift of the Auger line by 0.4 eV to higher kineti c energies is observed. This is attributed to a surface effect: The gr azingly incident protons undergo semi-planar channeling at the surface and mainly excite Auger electrons at topmost surface layer atoms. Com puter simulations which take into account surface steps corroborate th is interpretation.
