Item Gamma-Ray Spectroscopy(Addis Ababa University, 2018-08-03) Teffera, Yohannes; Tesfaye, Tilahun (PhD)Gamma-ray spectroscopy is the chief experimental technique of atomic physics and studies the high energy photons which are characteristic of the specific initial- and final-state nuclear energy levels, from radioactive decays. In this review the origin of gamma rays, interaction of gamma with matter, detection mechanism of gamma rays, gamma spectrometry, and applications of gamma-ray spectroscopy are reviewed. In this work, the current status of research in the development of CdZnTe, [NaI (Tl)], and high-purity Ge detectors, by a comprehensive survey on the material properties, the device characteristics, the different techniques for improving the overall detector performance and some major applications are revised.
