Kopsavilkums

We investigated the electron paramagnetic resonance (EPR), recombination afterglow and thermostimulated luminescence (TSL) of the X-irradiated LiBaF₃ crystals. After X-irradiation at 80 K, an EPR of the self-trapped hole centre V_K (F₂^-) oriented along the [110] axis is identified. X-irradiation at temperatures below 200 K results in a creation of a long-term temperature-independent afterglow - tunnelling luminescence (TL), with main emission bands at 300, 430 and 430 nm. The short wavelength TL bands are associated with the tunnelling recombination of the electron centre with the V_K centre, with thermal stability estimated to be about 130 K.
