Enhancement of analyte atomic lines with excitation energies of about 5 eV in the presence of molecular gases in analytical glow discharges

Abstract

Small amounts of hydrogen or oxygen in either argon or neon plasmas cause previously unexplained enhanced excitation of various analyte atomic lines with upper energies close to 5 eV. We suggest this enhancement is due to three body collisions involving two hydrogen or oxygen atoms and a sample atom.
