Abstract
Cerium bromide (CeBr3) scintillation crystal were studied and analyzed from the photon and electron response measurements. For photon response measurements, the radioactive source has been used for the energy range of 0.356 MeV ≤ E ≤ 1.332 MeV. The 137Cs source irradiated with gamma ray energy at 0.662 MeV was used for the electron response measurement using Compton coincidence technique. The variable angles (θ) would generate the gamma energies corresponding to a scattering angle of 30° to 120°. The results of number of photoelectron (Nphe) show responds to linear trends for photon and electron response. The light yield shows increase with increasing the photon and electron energy. The results showed the non-proportionality of photon response and electron response demonstrated good proportional properties of all energy ranges and as the result, the crystal is a promising candidate for gamma or X-rays detection.
