Abstract

The optical absorption (OA) and thermoluminescence (TL) of irradiated LiF : Mg, Ti (TLD-100) was studied as a function of the temperature of post-irradiation annealing using the I_m-T_stop and T_m-T_stop techniques. Computerised deconvolution was used to resolve the OA spectra into Gaussian bands and the TL glow curve into glow peaks. The dose response of the OA bands was also investigated. The filling and emptying rate "anticorrelation" and the behaviour with dose of the 5.6eV OA band on the one hand and 3.25 and 4.0eV OA bands on the other lead us to propose that the 5.6eV band trapping structure actively competes with the 3.25 and 4.0eV OA bands (or TL peaks 2 and 5) trapping structures and may be the "deep" competitor responsible for the supralinearity of these peaks.
