ABSTRACT:
An anode and a cathode are disposed in an opposing relation in a tubing in which an inactive gas is enclosed to form a discharge lamp by which an atomic spectrum is emitted. The cathode contains atomic spectrum emitting elements also serving to form the material of cathode. The discharge lamp is supplied with a high frequency power from a high frequency source and simultaneously with a direct current power from a direct current source. This causes the direct current discharge and high frequency discharge to be effected between a pair of electrodes in a superimposed manner. The atoms sputtered by the direct current are efficiently excited by the application of the high frequency with the result that atomic spectra with high brightness are obtained.
