An annealing study of neutron-irradiated germanium containing 2.2×1017 cm-3 antimony is described. The samples originally exhibit a temperature-independent resistivity below 10°K, corresponding to an impurity conduction band distinct from the conduction band of the germanium. Irradiation introduces a small activation energy ε2 in the resistivity below 10°K. The activation energy ε2 and the 78°K carrier concentration change anneal together at about 300°C. The annealing results are compared with those obtained on more pure germanium irradiated with x rays.
