Anotace
Unexpectedly large yields of positive and negative ions are produced when 2 and 5 keV Si+ is singly scattered from Cs adatoms on Al(100) and Si(111).This is in contrast with Li+, in which case the ions are almost completely neutralized. The Si+ ions likely result from valence electron resonant transfer (RCT) enhanced by promotion of the ionization level as it interacts with the Cs 2p level.
