  • Abstract
    Detailed fluorescence measurements of electron beam-excited high pressure mixtures of Ar/F2and Ar/NF3have been made in order to investigate the processes leading to the formation of Ar2F*. Three-body collisional quenching of ArF* has been identified as a major formation mechanism. The third-order rate constant for this reaction has been measured to be k_{1} = (1.2 \\pm 0.2) \\times 10^{-30} cm6. s-1. In addition quenching rates for collisional de-excitation of Ar2F* by argon and the fluoride donors NF3and F2have been determined. The radiative lifetime has been measured as 219 ± 15 ns. The possible formation of Ar2F* from long-lived excited argon neutrals when using intense excitation densities and low-donor pressures is also briefly discussed.
