Thermoluminescence recorded in a hyperbolic heating profile

Thermoluminescence (TL) glow curves corresponding to a hyperbolic heating p rofile are computed, for the first time, by solving a system of coupled dif ferential equations using the fourth-order Runge-Kutta method taking into a ccount the presence of thermally disconnected traps. The variations of the peak temperature and the symmetry factor with the change of the fractional- filling ratio have been studied, not only for the TL peaks obtained as a re sult of the solution of the coupled differential equations but also for TL peaks obeying Randall-Wilkins and Garlick-Gibson equations in a hyperbolic heating program. Finally, the validity of the plateau test has also been co nsidered.
