Nuclear resonance florescence (NRF) is a powerful tool for non-destructive assaying of nuclear materials. Detection system is a key issue for investigating nuclear materials using this technique. For a long time, Ge detectors were used because they have an excellent energy resolution but also have drawbacks of high cost and slow response time. On the other hand, LaBr3(Ce) detectors have high response speed and high detection efficiency as well as easy for assembly. However, a drawback of LaBr3(Ce) crystals comes from the unavoidable internal background levels near 2 MeV. This regime has great importance because it is very rich with235U and239Pu levels. We tested two different volume scintillators with 2.13 MeV quasi-monochromatic gamma-ray beam from the laser Compton backscattering (LCS) in National Institute of Advanced Industrial Science and Technology (AIST). We could clearly detect the NRF excitation level from11B at 2.13 MeV. For this level, the energy resolution for the small LaBr3(Ce) detector was 1.8% (FWHM), and 2.4% (FWHM) for the large LaBr3(Ce) detector. Potential of this scintillator for non-destructive assay of nuclear material identification is discussed in the light of our results.
