A description is given of the use of Li-drifted Ge detectors for high- resolution gamma spectroscopy. The detectors are used in the following manner: the photon enters the detector and annihilates into an electron-positron pair; the annihilation quanta escape from the detector; and the total energy of the electron-positron pair is lost in the detector. The detector thus reconds a peak at E -- 2m/sub 0/c/sup 2/, where E is the photon energy and mo is the electron rest mass. The method is useful only at high photon energies. The detectors in this application have energy resolutions of about 0.13%. (T.F.H.)
