Chemiionization of excited mercury atom with 253.7 nm irradiation was studied. Results on the system Hg–N<SUB>2</SUB> previously reported were further confirmed. It was found that CH<SUB>4</SUB> can also induce chemiionization of Hg atoms with 253.7 nm irradiation. The dependence of ionization current on CH<SUB>4</SUB> pressure and light intensity was investigated, the ionization current being found to be proportional to the square of light intensity and to increase with increase in CH<SUB>4</SUB> pressure up to 30 Torr, reaching a constant value. N<SUB>2</SUB> and CH<SUB>4</SUB> are considered to show a similar behavior in ionization current against pressure and light intensity, and other substances such as H<SUB>2</SUB>, He, CO, NO, Ar, C<SUB>2</SUB>H<SUB>4</SUB>, and 1-butene to give no appreciable ionization current. Thus the mechanism in which chemiionization proceeds through the collision of Hg(<SUP>3</SUP>P<SUB>1</SUB>) with Hg(<SUP>3</SUP>P<SUB>0</SUB>) is further confirmed.
