Figure 3
The angular dependences of the \({O}_{2}^{-}\) EPR line positions at the B rotation in the \((10\overline{1}0)\) plane (around b axis) in a neutron-irradiated α-Al2O3 crystal. The angle Θ is measured between the direction of B and the axis c. Solid lines and filled symbols—calculations, open circles—experimental points. The angle δ is between z axis of the \({O}_{2}^{-}\) and the crystallographic direction \([1\overline{2}10]\) (one of a axes).
