Abstract: The thermally induced decay of oxygen-deficient $E'$ centers in GeO$_2$ glasses and ceramics has been studied experimentally and theoretically. The electron emission effect, which accompanies the thermally induced decay of these defects, has been interpreted based on the Perel’-Karpus model for the multiphonon ionization of centers in an electric field. It has been established that the decay of $E'$ centers in amorphous and crystalline modifications of GeO$_2$ is reversible and occurs according to the thermal ionization mechanism.
