Abstract

Velocity distributions of In atoms in their ground (P122) and excited (P322) 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 P322 level is not significantly populated during sputtering and that the only path for population of this state is via laser-induced photodissociation of In2 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.
