An investigation has been made of the annealing properties of radiation- induced recombination centers in germanium. The annealing behavior of artimony- doped germanium is grossly different from that of arsenic-doped material. The experimental observations are explained on the following basis: The recombination level at 0.36 ev above the valence band belongs to the vacancy. In antimonydoped material the vacancy disappears by association with an antimony atom. This process does not occur in arsenicdoped material, and higher temperatures are required to produce annealing. It is thought that a trapping level, present only in arsenic-doped material, located 0.10 ev above the valence band might be due to an arsenic-interstitial pair. (auth)
