Abstract : A simple technique for fabricating lithium-drift germanium radiation detectors for use in gamma-ray spectroscopy is described in detail. Lithium-ion drift is conducted in room atmosphere at constant temperature and voltage for 470 hours to obtain a 2 mm thick sensitive region 7.5cm2 in area. One detector made by this method gives 10.3 kev (fwhm) resolution for the Cs137 662 kev gamma-ray. Leakage current at 77K and 65 volts reverse bias is 1.65 x 0.0000001 A.
