Abstract

By photolyzing XeF₂ using ArCl^* 175-nm radiation, the spontaneous radiative lifetime of the XeF(B ͢ X) band has been measured to be 14.25 ± 0.2 nsec. Also, the rates of two-body collisional deactivation of the XeF(B) state by Ne, Ar, and XeF₂ have been determined to be 7.7 X 10^-13 cm³ sec^-1, 4.9 X 10^-12 cm³ sec^-1, and 2.6 X 10^-10 cm³ sec^-1, respectively. A three-body quenching rate of 7.2 X 10^-32 cm⁶ sec^-1 was found for Ar. The large two-and three-body quenching rates of XeF^* by Ar suggest that Ne may be preferable to Ar as a diluent in high-pressure XeF (350-nm) laser mixtures.
