The surface trapping probability $S({E}_{i})$ of ${\mathrm{Na}}^{+}$ on Cu(001) has been measured for incident energies ${E}_{i}$ between 5 and 600 eV via resonant ion neutralization for both 45\ifmmode^\circ\else\textdegree\fi{} and 8\ifmmode^\circ\

Trapping probabilities for 5 eV to 600 eV Na+ incident at 45° along the 〈100〉 azimuth of Cu(001) have been measured. The measurement exploits the fact that the neutralization of scattered Na is very sensitive to Na particles trapped on the surfa

In this paper we present measured energy and angular distributions for Na{sup +} scattering from Cu(001) with incident energies ranging from 10 to 100 eV. Excellent agreement with the measured spectra over the full range of incident energies is achie

In recent experiments, we have succeeded in measuring thermal momentum fluctuations of surface atoms using hyperthermal (E2 of the quasisingle scattering peak for Na+ ions scattering from a Cu(001) surface, and found it to agree with a parameter-free

We use the Newns-Anderson Hamiltonian to describe many-body electronic processes that occur when hyperthermal alkali atoms scatter off metallic surfaces. Following Brako and Newns, we expand the electronic many-body wavefunction in the number of part

In this paper we present measured energy and angular distributions for 10–100 eV Na+ scattering from Cu(001). Excellent agreement with the measured spectra is achieved with a simulation that uses a model potential for the ion-surface interaction. F

We report the first evidence for trajectory-dependent neutralization of hyperthermal energy alkali ions scattered from a clean metal surface. We have scattered 7.5 and 50 eV ${\mathrm{Na}}^{+}$ from Cu(001) and found that, for atoms leaving the surfa

We have scattered low energy (100-400 eV) ${\mathrm{Na}}^{+}$ from a Cu(001) surface, and studied the peak in the energy spectra that corresponds to collisions in which the ${\mathrm{Na}}^{+}$ interacts primarily with a single Cu atom. This peak is b
