| Abstract: | A marked oscillator-strength decrease of the A band in KBr: Tl has been pointed out by means of thermally-modulated optical measurements throughout the temperature range 88–380°K. The experimental results suggest the existence of a clear correlation between the states responsible of the absorption bands and are discussed in order to clarify the role of the thermal perturbation upon Tl+ energy levels. |
