Abstract

Additionally to the well‐known 3380 Å band in the excitonic transitions of CsI at LHeT a new emission band at 2900 Å is reported and its behaviour is studied as a function of temperature. Experimental evidence is given which establishes the connection of the 2275 Å absorption band with localized exciton transitions. Measurements using ionizing β‐irradiation especially the temperature dependence of the β‐excited emission give further support to this model.
