Title: Observation of high electron emission yields following highly charged ion impact (up to Th sup 75+ ) on surfaces

Abstract

Double differential electron emission yields following the impact of fast (3.95{times}10{sup 7}cm/sec)Ar{sup 9,12,18+}, Ne{sup 9+}, Xe{sup 30,44+}, and Th{sup 70,75+} ions on Cu and Au targets have been measured. The electron emission is dominated by low-energy electrons ({lt}50 eV). It is found that the total yield, which rises to about 100 electrons per ion, is a nonlinear function of the total potential energy of the incident ion (up to about 200 keV).
