Isothermal annealing of germanium single crystals irradiated by γ-rays from Co 60 was studied. The variation of conductance with time was measured. The conductance curves are composed of three stages. To explain this fact, the model proposed by Fletcher and Brown may be employed with a certain modification. From the analysis of these curves, the activation energy of the direct recombination of vacancy interstitial pairs, that for the diffusion of interstitial atoms and that for the diffusion of vacancies were determined to be 0.765 eV., 0.741 eV. and 1.250 eV., respectively.
