Abstract : The kinetics of formation of the atomic vapors of silver in a cylindrical nickel thermionic cathode were investigated under various conditions. Intensity of the 3280.7 A silver line was used to determine atomic silver vapor concentrations. Using electroplated metallic silver, AgNo3 and AgCl, the latter with and without metallic lead and metallic bismuth, it was found that the silver vapor concentration was increased by reduction in the partial pressure of chlorine, through a substitution reaction between metallic lead or bismuth and AgCl, with a burst in intensity occurring in the silver emission line at the boiling temperature of the metal.
