在高强度γ源(HIγS)装置上，用准单色γ射线对235U靶进行了核共振荧光实验，共振能量为1733keV。在该测量中实现了由8个圆柱形探测器组成的LaBr3(Ce)探测器阵列，每个圆柱形探测器的长度为7.62 cm，直径为3.81 cm。此外，由四个探测器组成的高纯锗(HPGe)探测器阵列被用作使用LaBr3(Ce)探测器阵列进行测量的基准，每个探测器的相对效率为60%。用LaBr3(Ce)探测器测量的NRF能级积分截面与已有数据符合得很好。
A nuclear resonance fluorescence (NRF) experiment was performed on a 235U target with quasi-monochromatic γ-rays at the High Intensity γ-ray Source (HIγS) facility using a 1733 keV resonant energy. A LaBr3(Ce) detector array consisting of eight cylindrical detectors, each with a length of 7.62 cm and a diameter of 3.81 cm, was implemented in this measurement. Moreover, a high-purity germanium (HPGe) detector array consisting of four detectors, each of which has a relative efficiency of 60%, was used as the benchmark for the measurement taken using the LaBr3(Ce) detector array. The integrated cross section of the NRF level, measured with LaBr3(Ce) detectors, showed good agreement with the available data.
