Abstract
Rate constants for the collisional deactivation of Pb 6p2(3P2) and (3P1) metastable states are reported over the temperature range 300 to 600 °K. Quenching data over this temperature range were obtained for relaxation by Ar, Xe, H2, D2, N2 and by Hg at 373 °K. These results were obtained in a temperature controlled, flash photolysis apparatus using tetramethyl lead as a precursor and time resolved atomic resonance absorption techniques for monitoring the 3P2 and 3P1 metastable states of interest.Keywords
