摘要：
A nuclear resonance fluorescence (NRF) experiment was performed on a U-235 target with the quasi-monochromatic gamma-ray at High Intensity gamma-ray Source (HI gamma S) using the 1733 keV resonant energy. A LaBr3(Ce) detector array consisting of 8 cylindrical detectors, each has length of 7.62 cm and a diameter of 3.81 cm, in diameter was implemented in this measurement. Moreover, high purity germanium (HPGe) detector array consisting of 4 detectors each has a relative efficiency of 60 %, was used as a benchmark for the measurement taken by LaBr3(Ce) detector array. The integrated cross-section of the NRF level measured with LaBr3(Ce) detector showed good agreement with the available data. Consequently, LaBr3(Ce) detector could be feasible to use as a detector for the special nuclear material inspection system.
