Some atomic collision processes which influence the emission of radiation from gas discharge sources are discussed briefly The processes are divided into the following categories (1) Excitation of an atom by electron impact, (a) direct (from the ground state) and (b) indirect (from an excited state); (2) Collisions between excited atoms; (3) Transfer of excitation, and (4) Electron-ion recombination The relative importance of these reactions is discussed and possible consequences with regard to spectrochemical analyses are considered.
