| Zusammenfassung | Optical absorption measurements were performed on LiF:Mg and LiF:Mg, Ti crystals after irradiation and various thermal treatments. From the close correlation between the 4.0 and 5.5 eV absorption bands introduced by the Mg dopant a model for the trapping process in thermoluminescent LiF is developed basing on Z centers. Traps initiating main glow peak 5 are assumed to be Z2 centers being produced by irradiation via Z0 and Z3 centers in a two step process. The model explains radiation sensitization as well as the necessity for pre‐irradiation annealing in thermoluminescence dosimetric application.
