Abstract :
Detailed fluorescence measurements of electron beam-excited high pressure mixtures of Ar/F2 and Ar/NF3 have been made in order to investigate the processes leading to the formation of Ar2 F*. 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 
cm6. s-1. In addition quenching rates for collisional de-excitation of Ar2 F* by argon and the fluoride donors NF3 and F2 have been determined. The radiative lifetime has been measured as 219 ± 15 ns. The possible formation of Ar2 F* from long-lived excited argon neutrals when using intense excitation densities and low-donor pressures is also briefly discussed.
