[en] Dissociative and Penning reactions of metal-bearing compounds with thermal energy metastable atoms and molecules have been increasingly used to provide ensembles of inter-mediate metal compounds or free metal atoms in their ground or excited state. Such reactions are particularly important in laser and plasma vapor deposition processes. We employ both a flowing afterglow and metastable beams to obtain cross-sections for the various kinetic processes which occur when a metal compound and a metastable species interact. Elastic, total quenching, dissociative, Penning, and flourescence cross-sections are obtained for a number of systems. (Author)
