Another technique for the determination of the total quenching cross section of thallium on mercury fluorescence is described. Results from a single run using this method are compared to previously described results. The procedure for determining the total quenching crosssection is a From the absorption data on the mercury only cell and a mercury-thallium cell at the same temperature determine the mercury number density in the mercurythallium cell. b From the number density of mercury atoms in the cell and the data on the mercury only cell determine the expected scattering, I, at each temperature. c Correction for slight changes in geometry between the cells and correction for the transmission of the windows will be a simple multiplicative constant which can be determined at low temperatures, where there is not enough thallium vapor to give any appreciable quenching thus the scattering I can be determined.
