Formation and quenching processes, as well as the optical emission characteristics of Xe/sub 2/Br*, centered at 440 +- 30 nm were investigated for electron beam pumped mixtures of argon, xenon, and several different bromine donors. Three-body collisional quenching of XeBr* was identified as the primary formation mechanism for the triatomic species. Quenching rates for Xe/sub 2/Br* and XeBr* were measured and the Xe/sub 2/Br* radiative lifetime was determined to be 245 +- 30 ns.
