Velocity distributions of In atoms in their ground (/sup 2/P/sub 1/2/) and excited (/sup 2/P/sub 3/2/) states ejected from In foils by bombardment with 5-keV Ar/sup +/ ions are measured with a multiphoton resonance-ionization technique. We show for the first time that the /sup 2/P/sub 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/sub 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.
