Abstract
Thermoluminescence processes in KCl:Ag (14 ppm) crystals following room temperature γ-irradiation (20 Mrad for 50 h) has been examined. Silver impurities induce “shallow” traps and the processes follows neither the first-order nor the second-order kinetics. Recombination processes show both intrinsic factors (460 nm) and extrinsic factors (263 nm and 700 nm). Electron-hole recombination occuring at some stage during interstitial-F-centre recombination, favours tunneling.
