Stable glow discharges have been demonstrated in thallium-mercury gas mixtures at mercury densities of 3 x 10/sup 19/ and temperatures of 500--900 /sup 0/C. These discharges have shown themselves to be highly efficient in producing excited Tl (7/sup 2/S/sub 1/2/) atoms and Tl-Hg B/sup 2/summation/sub 1/2/ excimer molecules. Discharge efficiency as high as 30 +- 10% in producing Tl (7/sup 2/S/sub 1/2/) and Tl-Hg B/sup 2/summation/sub 1/2/ points to the possibility of the creation of a Tl-Hg excimer laser operating at similar efficiencies. These highly efficient discharges are thought to be due to very fast transfer of energy from mercury excimers into Tl-Hg. The transfer cross section from excited molecular mercury to Tl (7/sup 2/S/sub 1/2/) and Tl-Hg excimers is found to be approximately 1.2 x 10/sup -14/ cm/sup 2/.
