摘要：

The interpretation of the EPR signal appearing after interaction of oxygen with the MnO-MgO system (Mn<1.0 at.%) has been performed. The attribution of the signal to O2- species stabilized on Mn2+ ions situated at the surface of MnO-MgO was confirmed from the g factors, as well as from the change in the intensity of particular lines of the Mn2+ hyperfine structure.
