Abstract: | High-purity germanium (HPGe) and lithium drifted germanium (Ge(Li)) detectors have been the detector of choice for high resolution
gamma-ray spectroscopy for many years. This is primarily due to the superior energy resolution that germanium detectors present
over other gamma-ray detectors. In order to perform quantitative analyses with germanium detectors, such as activity determination
or nuclide identification, one must know the absolute full-energy peak efficiency at the desired gamma-ray energy. Many different
methods and computer codes have been developed throughout history in an effort to predict these efficiencies using minimal
or no experimental observations. A review of these methods and the computer codes that utilize them is presented. |
