Quenching of Excited Zinc(3PJ) and Zinc(1P1) Atoms by Several Gases

Abstract

Abstract The intensities of the 307.6 nm and 213.9 nm resonance lines of zinc were measured at different pressures of several gases, and the quenching rate constants were determined on the basis of the Stern-Volmer plots. The quenching cross-sections obtained here were compared with those for mercury and cadmium. The simple chargetransfer curve-crossing theory proposed by Breckenridge and Renlund for the quenching of excited cadmium and mercury atoms by N2, CO, CO2, and so on was found to be useful for the quenching of excited zinc atoms, as well. Isotope effects on the quenching of Zn(3PJ) and Zn(1P1) by H2 and D2 were also discussed.
