Abstract :
The radiative lifetime of the blue C \\rightarrow A transition of XeF has been measured to be 93 ± 5 ns by monitoring the exponentially decaying 460 nm emission following rapid electron impact dissociation of XeF2. By varying the XeF2partial pressure, the rate constant for quenching of XeF ( C ) by XeF2was determined to be (1.8 \\pm 0.5) \\cdot 10^{-10} cm3. s-1. Finally, knowledge of the XeF B and C state lifetimes yields a revised value of 610 ± 60 cm-1for the B to C state energy defect.
