Some aspects of the kinetics of formation of triatomic halogenides of rare gases

The formation of triatomic excimer molecules Rg₂X and Rg’RgX by VUV excitation of mixtures of halogens with rare gases is discussed. The remarkable simplicity of the electronic structure and kinetics of these molecules offers interesting possibilities for studying the role of different collisional processes in recombination in the high-and low-pressure limits.
