Spectral distributions of KI, KI-Tl, Kf-In crystals under gamma excitation at liquid nitrogen temperature and at room temperature were investigated. The results show for KI, one ultraviolet emission band with lambda m approximately -370 m approximately ; for crystals with high Tl concentration, one activated band with lambda m approximately - 406 m mu ; for crystals with small Tl concentration, the band lambda m approximately -382 m mu , assumed to be composed of two bands, one thallium and the other ultraviolet. For crystals activated by small concentration of In there are two bands. one ultraviolet and the other an activator long-wave band. With increased In concentration, the intensity of the ultraviolet band diminishes and the activator band increases. At very large concentrations of In and Tl the ultraviolet band completely disappears. (R.V.J.)
