Abstract
The KrF* and Kr2F* fluorescence emissions from e-beam excited F2/Kr/Ar mixtures were measured over the temperature range of 315°–420 °K, at total densities of 1, 2, and 3 amagat. These data were used in conjunction with kinetic model calculations to evaluate the temperature dependence of three-body quenching reactions of the type: KrF*+R+M→RKrF*+M, where R≡Ar, Kr, and M≡Ar, Kr. The decrease in the three-body rates with increasing temperature deduced from the experimental data, agrees to within 15% of that calculated by using classical phase-space theory.
