Abstract
A novel technique to improve the efficiency of mercury bromide lasers is described. N2(A-X), N2(B-A), and N2(C-B) emission band systems are observed besides atomic lines of sodium when a microwave discharge is passed through a flowing vapour of NaN3 in a quartz tube. The HgBr (B-X) band system and atomic mercury lines also are detected during collisions of N2(A) both with HgBr2 and CH3HgBr. In collisions involving CH3HgBr and N2(A), the CH(A-X) and CN(B-X) emission band systems are found as well. From the integrated intensity of the most intense band (0, 22) at 502nm of the HgBr (B-X) transition, the ratio of the rate of formation of HgBr (B-state) during collisions of HgBr2 and CH3HgBr with N2(A) has been determined to be 2·3:1.
