摘要: Abstract In this work, the results on determination of kinetic parameters using method deconvolution glow curves obtained from LiF doped with Mg 2+ ions, after having been irradiated to 5, 10 and 25 Gy 60 Co gamma radiation, corresponding range TL-vs-dose response linearity, are presented. The is performed two functions by asymptotic series based approximation continued fractions. curve studied material shows a dosimetric peak at 518 K three peaks very low intensity 383, 423 463 K, all general-order kinetics. Kinetic both methods showed that values kinetics, b , energy traps, E factor frequency, s do not differ significantly. However, figure merit, FOM, second derivative criteria indicate accuracy calculations improves considerably.
