Electron paramagnetic resonance studies have been performed in oxygen‐doped germanium. Room‐temperature irradiation with 2‐MeV electrons produces a paramagnetic center ofS= ½ whosegtensor has (011), (01¯1), (100) principal axes. Thegshifts are consistent with this being the germaniumAcenter, i.e., an oxygen‐vacancy complex. Infrared absorption bands at 766, 807, and 847 cm−1may be associated with this defect.
