Title

Deexcitation Model for Sputtered Excited Neutral Atoms

Abstract

Velocity distributions of In atoms in their ground ( 2 P 1 2 ) and excited ( 2 P 3 2 ) states ejected from In foils by bombardment with 5-keV Ar + ions are measured with a multiphoton resonance-ionization technique. We show for the first time that the 2 P 3 2 level is not significantly populated during sputtering and that the only path for population of this state is via laser-induced photodissociation of In 2 during the detection process. A new deexcitation model for sputtered excited neutral atoms is proposed which is based on the electronic localization of the fine-structure orbital.
