ABSTRACT:
A light source for Zeeman spectroscopy wherein an anode in an ionizable gas is used for ion bombardment of a cathode having materials therein whose spectra is to be observed. The anode and cathode are mounted in a magnetically permeable housing which fits snugly between pole pieces of a magnet such that the magnetic field between pole pieces is perpendicular to the electric field between the anode and cathode so that the arc discharge therebetween is spacially limited to a narrow dimension, i.e., a line, for improved Zeeman atomic absorption spectroscopy.
