Title: Path-Dependent Neutralization of Multiply Charged Ar Ions Incident on Au(110)

Journal Article · · Physical Review Letters

Using a time-of-flight technique we have investigated the backscattering of 5keV Ar{sup 2+} and Ar{sup 11+} projectiles from Au(110). A strong dependence on target azimuth is found for the neutral flux resulting from (quasi)binary projectile collisions with target atoms, while for the charged components only a weak dependence is seen. A deconvolution of the observed dependences based on trajectory simulations clearly shows site-specific neutralization differences between the various possible binary collisions occurring with surface atoms. Such differences must be properly accounted for in order to permit meaningful comparison with theory.
