In this paper, we report on a new scintillator, cerium bromide (CeBr3), for gamma-ray spectroscopy. Crystals of this scintillator have been grown using Bridgman process. In this material Ce3+is an intrinsic constituent as well as a luminescence center for the scintillation process. Samples of CeBr3showed high light output (~68000 photons/MeV) and fast decay constant (~17 ns). Furthermore, they exhibited excellent energy resolution for gamma-ray detection. For example, energy resolution of137Cs source) at room temperature. High timing resolution (3-photomultiplier (PMT) and BaF2-PMT detectors operating in coincidence using 511 keV positron annihilation gamma-ray pairs
