| Abstract: | This work is devoted to an analysis of thermal decay processes of the stable colour centres (CC) created in gadolinium gallium garnet (GGG) Gd3Ga5O12, crystals under irradiation by gamma-quanta (E=1.25 MeV, D=106 Gy). An analysis of the model of CC accumulation under irradiation as well as an isochronous heating model is presented. The decay activation energy (Δ E) for O? and F centres in GGG crystals is calculated in accordance with this model. |
