Abstract

An experimental technique has been developed to determine the fraction of metastable ions present in beams. The technique involves measurement of total electron capture cross sections from neutral species where individual ground and excited state reactant ion cross sections are known. Metastable C II ion abundances from electron impact ionization of various molecules have been obtained.
