Possibilities of Using CdZnTe and CeBr 3 Crystals for Measuring Photon Radiation in a Wide Energy Range

New semiconductor detectors based on CdZnTe and CeBr 3 crystals are tested. A spectrometer facility consisting of CdZnTe, CeBr 3 , and Si (for α–γ measurements) detectors is assembled for verification tests. The main parameters of the detectors such as energy resolution FWHM/ E γ [keV] and detection efficiency (%) are investigated and measured. The possibilities of measuring photon radiation in a wide energy range are verified. γ–γ and α–γ coincidences are measured using the detectors. The results of the measurements show that the detectors can be used to study nuclear reactions and properties of reaction products.
