SENSITIZED FLOURESCENCE

Abstract

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.
