“…4b. For lack of proper Cu-Li calculation we adopt for a qualitative discussion a Re(W=-4.96eV)-Li calculation [21] of E(y), F(y) and a more general discussion of these phenomena from [22]. When a Li-ion (atom) is approaching the Cu-surface with E a it reaches a distance of closest approach r o =Yo which is calculated for leV<El<100eV on the basis of a planar potential to be 0.2nm>yo>0.015nm.…”

“…When assuming the approximation of a temperature T=0 one has to consider for the receding ion only the resonance neutralization at energies below the Fermi-level; i.e. from distance Yc where E'~= W. For an estimation of y~ we neglect all dynamic effects due to the large velocity component parallel to the surface and find in [22] …”

Band structure effects in high energy ion beam surface interaction at grazing incidence

The analysis of charge state distributions after the interaction of fast Li-and N-ions with a surface at grazing incidence at energies between 50 and 350keV yields for Li a strongly suppressed and for N an enhanced fraction of neutrals in comparison to the beam-foil interaction. These findings are supported by corresponding alkali-spectra which are dominated by lines from transitions in singly ionized atoms. The experiments are consistently interpreted in terms of a two step model: (1) collisional excitation in the close vicinity of the surface and (2) modification of this population by resonant electron transfer from (to) non localized states in the conduction (valence) band to (from) the ion. The model is also applied to interpret recent beam-foil experiments where preferential populations of Rydberg levels in highly ionized atoms were found.

A phenomenological description of one‐electron transfer leading to ion neutralization in ion‐surface scattering is summarized. A perturbative treatment using an effective interaction in the Anderson‐Newns Hamiltonian is then reviewed, and the conditions under which the perturbative series has fast convergence are explored in terms of the electronic and dynamical properties of the collision system. Calculational results are discussed for proton neutralization at different alkali‐halide surfaces. In the case of negative‐ion formation and hence two‐electron transfer to the incoming projectile ion, the Anderson correlation energy U is included in the analysis. Calculations of the probability of negative‐ion formation are in qualitative agreement with experiments on the conversion of H+ (D+) to H− (D−) by scattering from a cesiated W(110) surface. The interplay between temperature effects and U are discussed. Improvements on the calculations by incorporating the image potential into the ionic energy level shift are considered.
