Popis:	The HgBr(B–X) transition forms the basis of an efficient laser at 502 nm. The HgBr(B) state is produced by electric discharge in gas mixtures containing HgBr2. We report measurements of the HgBr(B–X) fluorescence efficiency as a function of electric field in electron beam sustained HgBr2/noble gas discharges. These measurements indicate that the dominant HgBr(B) formation channel is via direct electron impact on HgBr2 by the process HgBr2+e− → HgBr(B)+Br+e−.A Boltzmann analysis is used to derive an empirical cross section for this process.
