Inelastic Collisions Between Excited Alkali Atoms and Molecules: Vi. Sensitized Fluorescence in Mixtures of Sodium with CH4, CD4, C2H2, C2H4 and C2H6

摘要

The total cross sections for 3 doublet P1/2 to 3 doublet P3/2 mixing in sodium, induced in collisions with CH4, CD4, C2H2, C2H4 and C2H6 molecules, have been determined using the method of sensitized fluorescence. The sodium vapor - molecular gas mixtures were irradiated with each Na(D) component in turn, and the cross sections were obtained from measurements of relative intensities of the two D-components present in the fluorescent light.
