- Аннотация: The recovery of radiation damage induced by 156-МeV 132Хе and 2.25-GeV 197Au ions (fluences between 6.6 × 1010 and 2 × 1012 ions/cm2) in MgAl2O4 single crystals has been investigated via stepwise (isochronal) thermal annealing procedure. The integral of elementary bands of radiation-induced optical absorption (result of spectra decomposition into Gaussians) has been considered as a concentration measure of relevant structural defects. The general trends of the multistage annealing kinetics of the oxygen-vacancy-related F+ and F centers (430–850 K) as well as complex cation-related defects responsible for absorption bands peaked at 5.9, 6.6 and ∼7 eV (ends above 1000 K) have been considered. The features of the annealing kinetics of these defects induced by the xenon or gold ions with different values of mean energy loss along the ion trajectories (13.5 and 30.4 keV/nm, respectively) and fluences have been analyzed.
