• The electronic structure of various types (one-center, two-center, and dimer corn-plex) of self-trapped excitons (STE's) in alkali halide crystals containing heavyhalogen impurity atoms, has been studied by the extended-ion method (developedearlier for STE's in pure alkali halides) coupled with a CNDO code. Results of thecalculations for KCI:I, RbC1:I, and KCI:Br are generally in satisfactory agreementwith experiment. In particular, two distinct configurations have been found for thetwo-centre type STE's, which accounts for the blue and the blue'-green emissionbands. A general discussion of defect (F-H pair) formation mechanism in thesesystems, consistent with experimental observations, has also been presented.
