Abstract

TOF spectra of scattered neutrals and ions for 3 keV He+, Ne+, and Ar+ bombardment of La and adsorbate covered La surfaces show that the scattered ion fractions are 21.1% and 10.7% for Ar+ on clean and adsorbate covered La, respectively, and < 1% for all of the other systems. These results are consistent with a model in which Auger and resonant neutralization (AN and RN) transitions govern the ion survival probability.
