Abstract

The full-energy peak efficiency calibration and the energy resolution measurements of the 2 in . × 2 in .LaBr3γ -ray detector are presented for γ-ray energies in the 700 keV-17.6 MeV range. Measurements were done using a combination of proton-capture nuclear reactions on 27Al, 23Na, 39K, 7Li and 11B for high-energy γ-rays, and radioactive sources such as 60Co and 152Eu for the lowest energies. At high energies, two γ-rays in a cascade from proton resonance capture were employed using Al, Na2 WO4, K2 SO4 and LiBO2 targets. The obtained results were compared to the simulations performed using a GEANT4 code.
