Resonance transfer of electrons in the reflection of atoms from metal surfaces

Measuring correlated-electron effects with low energy alkaline earth ion scattering

“…A rise in surface temperature increases the electron occupancy above the Fermi energy, which then leads to an increase in the measured neutralization within the RCT model [7][8][9][10][11]. This often has a negligible effect on the measured neutralization rates, however, as the magnitude of the additional occupancy is small compared to the typical energy scale in ion scattering.…”

Correlated Electron Effects in Low EnergySr+Ion Scattering

“…Finally, the work function of the sample was monitored as its temperature was adjusted, and the variations in going from 300 to 873 K were found to be negligible, which is a strong indication that the surface structure does not change with temperature. A rise in surface temperature increases the electron occupancy above the Fermi energy, which could then lead to an increase in the measured neutralization within the RCT model [11][12][13][14]. This has sometimes been shown to have a negligible effect on measured neutralization rates, however, as the magnitude of the additional occupancy is usually small compared to the typical energy scale in ion scattering.…”

Thermally Enhanced Neutralization in Hyperthermal Energy Ion Scattering

“…The effects of surface temperature or T S on neutralization at a surface, however, have typically been ignored experimentally. In fact, few quantitative measurements [3,4] have explored the role of T S in determining P 0 , despite the many theoretical studies [5,6,7,8,9,10,11,12,13] that have been devoted to the subject.…”
