MULTIELECTRON EFFECTS IN THE INTERACTION OF F- IONS WITH AG(110)

In this paper an experimental investigation of the survival rates of n egative fluorine ions scattered against an Ag(110) surface is presente d. A theoretical analysis shows that the charge transfer dynamics can be attributed to resonant tunneling. We show that the results can be w ell described using a time-dependent Anderson model. We discuss the ro le of many-electron interactions and show that they must be included f or an accurate modeling of the charge transfer. (C) 1998 Elsevier Scie nce B.V. All rights reserved.
