The energy and spectral parameters of emission of a barrier discharge in chlorine and its mixtures with inert gases are studied experimentally. The barrier discharge in chlorine was homogeneous at pressures up to ∼ 9 Torr and its spectrum contained the 32g -→ 32u, 32g32u + and 1u +1 g + bands of Cl2* molecules. After the addition of an inert gas, the 257.8-nm 32g32u band made the main contribution to the spectrum. The maximum efficiency and power of the Cl2 excilamp were obtained for the chlorineargon mixture and amounted to 0.7 % and 1.3 W, respectively.
