Low-energy (0.12 keV) neon and helium have been scattered from Si(001), Al(111), and polycrystalline Mg surfaces to investigate collision-induced electronic excitation. It is found that a large contribution of (re)ionization is responsible for almost identical Ne+ spectra between Ne+ and Ne0 incidence, whereas Ne2+ originates mainly from Ne+ and very little is created directly from Ne0. The predominance of one-electron excitation over two-electron excitation is characteristic of surface scattering and is basically caused by the band effect of the energy-level crossing. © 1995 The American Physical Society.
