Abstract

Abstract: Nowadays, semiconductor detectors, in general, and high purity gemanium detectors (HPGe) in particular are widely used in various fields of experimental nuclear physics. In gamma ray experiments, energy resolution and the efficiency are very important characteristics of detectors. In this paper, the gamma standard sources such as 137Cs, 57Co, 60Co, 54Mn, 133Ba, and 109Cd were used to study the characteristics of the BEGe 3050 detector. The methods of determining the absolute photo- peak efficiency and the dependence of the energy resolution on γ-ray energy are presented.
