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 ...
Thermal annealing and transformation of dimer F centers in neutron-irradiated Al2O3 single crystals
(Elsevier B.V., 2021)
The precise study of the thermal annealing of the F2-type dimer defects, being under discussion in the literature for a long time and responsible for the number of absorption bands below 4.5 eV, has been performed in ...
Atomic, electronic and magnetic structure of an oxygen interstitial in neutron-irradiated Al2O3 single crystals
(Nature Research, 2020)
A single radiation-induced superoxide ion O2- has been observed for the first time in metal oxides. This structural defect has been revealed in fast-neutron-irradiated (6.9×1018n/cm2) corundum (α-Al2O3) single crystals ...
