Abstract: | The full-energy peak efficiency calibration and the energy resolution measurements of the LaBr3 γ-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 , , , and for high-energy γ-rays, and radioactive sources such as and for the lowest energies. At high energies, two γ-rays in a cascade from proton resonance capture were employed using Al, Na2WO4, K2SO4 and LiBO2 targets. The obtained results were compared to the simulations performed using a GEANT4 code. |
