Abstract
We present the results of a study of H-formation in collisions of 1-4 keV hydrogen ions with a Si surface. Measurements of scattered negativ e ion fractions are reported. These are found to be of the same magnit ude as for clean metal surfaces like Al. A dynamic velocity-dependent effect in electron capture is observed. A velocity-dependent, nonreson ant, charge-transfer process involving localized dangling-bond surface states is invoked to explain this observation.
