Kinetic model of the XeBr rare-gas monohalide excimer laser

A kinetic model of the XeBr rare-gas monohalide excimer laser is presented. Agreement of predicted and observed side emission from low-pressure Xe:Br2 mixtures was used to determine rate constants for the formation of XeBr* from Xe* and Br2 (2.0±0.4×10−9 cm3/sec) and the quenching of XeBr* by Br2 (8±2×10−10 cm3/sec), as well as the radiative lifetime of XeBr* (17.5±2.5 nsec).
