In the Auger neutralization regime, the ion yield is determined by scattering from the outermost atomic layer. For Cu(110) P+ exceeds that for polycrystalline Cu by up to a factor of 2.5, thus exhibiting a strong crystal effect. It is much less pronounced at higher energies, i.e., in the reionization regime. However, there a completely different angular dependence of the ion yield is observed for poly- and single crystals, due to massive subsurface contributions in nonchanneling directions.This work was partially supported by the Austrian Science Fund FWF, project number P16469.Peer reviewedAmerican Physical Society200820082008info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_65011184968 bytesapplication/pdfhttp://hdl.handle.net/10261/7293reponame:DIGITAL.CSIC.
