摘要：

We report experimental results on the charge equilibration process of both He+ and He++ ions at energies from 0.4 to 1.5 MeV in the Si[100] direction. The characteristic equilibration distance increases with energy from 3 nm to about 10 nm at the highest energy. The experimental findings are compared with Monte Carlo calculations describing the particle motion in a continuum potential for the [100] channel. (C) 2000 Elsevier Science B.V.
