✦ Synopsis
We report a study of the rtet coiI1slona1 removal of HgBr(X %fn, U" = 22) by Oz. N2. Hz, He, Ne, Ar, K&and Xe. Z&e coefficients are large, mdrcatmg that deativation of the lower laser levels m the HgBr(B + X) lasers proceeds efiiciently.

The fast biiolecular reaction HgBr + Br2 -+ HgBr2 -I-Br is shown to be responsible for the observed mpid and efiicient regeneration of HgBrZ in cyclic operation of the repetitively pulsed HgBr photodissociation laser. The rate constant for this reaction has been measured to be (7.7 + 0.6) X lo-" cm3
