Resumen
Recombination luminescence (RL) and RL-detected electron paramagnetic resonance (RL-EPR) in BaY2F8 single
crystal has been investigated after irradiation with X-rays at low temperature. The recombination process, which
lasts for several hours at 4 K, results in several broad bands in the RL spectrum. RL-EPR spectra show pronounced
angular dependences on crystal orientation relative to external magnetic field. Based on the determined spin-Hamiltonian parameter values the recombination centres have been proposed to be F-type electron and self-trapped
hole (VK) centres. Conselho Nacional de Desenvolvimento Cient??fico e Tecnol??gico (CNPq) CNPq: 421581/2016-6
