The dependence of the nuclear resonance fluorescence (NRF) yield on the target thickness was studied. To this end, an NRF experiment was performed on $^{238}$ U using a laser Compton back-scattering (LCS) -ray beam at the High Intensity -ray Source facility at Duke University.

The performance of LaBr $_{3}$ (Ce) to measure nuclear resonance fluorescence (NRF) excitations is discussedin terms of limits of detection and in comparison with high-purity germanium (HPGe)detectors near the 2 MeV region where many NRF excitation levels from special nuclear materials are located. The NRF experiment was performed at the High Intensity Gamma-ray Source (HIGS) facility of Duke University. The incident -rays, of 2.12 MeV energy, hit a B $_{4}$ C target to excite the $^{11}$ B nuclei to the first excitation level. The statistical-sensitive non-linear peak clipping (SNIP) algorithm was implemented to eliminate theback ground and enhance the limits of detection for the spectra measured with LaBr $_{3}$ (Ce). Both detection and determination limits were deduced from the experimental data.

A nuclear resonance fluorescence (NRF) experiment was performed on a $^{235}$ U target with quasi-monochromatic -rays at the High Intensity Gamma-ray Source (HIGS) facility of Duke University using a 1733 keV resonant energy. A LaBr (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 LaBr (Ce) detector array. The integrated cross section of the NRF level, measured with LaBr (Ce) detectors, showed good agreement with the available data.
