Abstract

Production of the ionic spectrum of metal atoms forming the cathode of a hollow cathode glow discharge is affected by gas phase charge transfer reactions. This is observed in a copper hollow cathode lamp in separate experiments for helium, neon, argon, krypton, and xenon fill gases. The copper ionic line -atomic line emission intensity ratio is increased with fill gases which have metastable or ionization energies greater than the excitation energy of the copper ionic line. Potential application of ionic line emission sources to atomic (ion) fluorescence in inductively coupled plasmas is presented.
