Accumulation of radiation defects and modification of micromechanical properties under MgO crystal irradiation with swift 132Xe ions
(Elsevier B.V., 2020)Accumulation of F-type defects under irradiation of MgO crystals by 0.23-GeV 132Xe ions with fluence varying by three orders of magnitude has been investigated via the spectra of optical absorption and low-temperature ... -
First Principles Simulations on Migration Paths of Oxygen Interstitials in MgAl2O4
(Wiley-VCH Verlag, 2018)Thermal stability of the primary electronic defects – F‐type centers – in oxide materials is controlled by their recombination with much more mobile complementary defects – interstitial oxygen ions Oi. Thus, the study of ... -
Kinetics of dimer F2 type center annealing in MgF2 crystals
(Elsevier B.V., 2018)In this paper, we analyzed experimental annealing kinetics of the primary electronic F centers and dimer F2 centers observed in MgF2 at higher radiation doses and temperatures. The developed phenomenological theory takes ... -
Kinetics of the electronic center annealing in Al2O3 crystals
(Elsevier B.V., 2018)The experimental annealing kinetics of the primary electronic F, F+ centers and dimer F2 centers observed in Al2O3 produced under neutron irradiation were carefully analyzed. The developed theory takes into account the ... -
Peculiarities of the diffusion-controlled radiation defect accumulation kinetics under high fluencies
(Elsevier B.V., 2020)Theory is developed for kinetics of the diffusion-controlled radiation defect accumulation in crystalline solids under high fluencies taking into account recently observed correlation between the defect diffusion energy ... -
Recombination luminescence of X-ray induced paramagnetic defects in BaY2F8
(Elsevier B.V.Journal of Luminescence, 2020)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 ...
