Low-Energy Collisions of Excited Atoms.

Abstract

Alkali-halogen and alkali-alkali systems have been studied including Sodium-Bromine, Na-Chlorine, Na-Na, and Na*-Na. All atoms were in the ground state except Na*, which represents Na in the first electronic state. Merging-beams techniques were used for the former systems and beam-gas for the latter. Laser radiation was employed to generate Na* either in the beam or the gas. Theoretical predictions of cross sections for Na-Br and Na-Cl have been made by Faist and Levine and are in good agreement with these experimental results. Comparisons of cress sections for Na-Na and Na* show that electronic excitation of Na greatly enhances ion-pair production. Keywords: Collisions.
