Metastable Interactions: Dissociative Excitation.

Abstract

The work reported here is concerned with the interaction between thermal energy metastable atoms and molecules and other atoms and molecules in a beam or in a flowing afterglow. The importance of reactions involving metastable species can be traced to the relative ease with which energy can be stored in ensembles of metastable atoms and molecules and the wide variety of reactions in which they can participate. Of particular interest are those processes which involves energy transfer from the metastable system to a second species which results in excited states which fluoresce. Two principal experimental methods have been used: (a) Metastable beams crossed with a target species, (b) Fast flowing rare gas and nitrogen afterglows. A wide variety of metal halogen, Group II metastable beams crossed with a target species, (b) Fast flowing rare gas and nitrogen afterglows. A wide variety of metal halogen, Group II metals, methane and silane have been reacted with helium, argon and nitrogen metastables. Originator supplied keywords include: Energy transfer; Collisions; Radiation; Metastables. (Author)
