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.
