Study of Metastable Rare Gas Collisions with Molecules.

Abstract

This report summarizes an experimental and computer-modeling investigation of reactive and inelastic scattering of fast metastable rare gas atoms (He* (21S), He* (23S), and Ar*) by O2 and I2 target molecules. Similarities to (and difference from) analogous alkali atom interactions with halogen and oxygen molecules were probed. Processes investigated and characterized included ion-pair formation, ion-pair mediated vibrational excitation, and Penning ionization. Coincidence techniques were developed that allowed the first double-differential cross section measurements of a Penning process in a triatomic system. (Author)
