L0289001 28 INC-SOURCE (LCS) The facility provides quasimonochromatic photon L0289001 29 beams from laser-Compton backscattering (LCB) in the L0289001 30 MeV range. The machine was operated in a new L0289001 31 high-resolution mode. It reduces the spectral L0289001 32 bandwidth of the photon beam to about 1.8% by L0289001 33 optimizing the electron beam parameters and using L0289001 34 narrower apertures for the Compton-scattering L0289001 35 geometry at the expense of photon-flux intensity. L0289001 36 DETECTOR (HPGE,SCIN) Four high-purity germanium (HPGe) L0289001 37 detectors, four lanthanum bromide (LaBr3) detectors. L0289001 38 SAMPLE (60-ND-150,ENR=0.936) Target composed of 11.583(1) g L0289001 39 of Nd2O3 enriched to 93.60(2)% of 150Nd. L0289001 40 METHOD Nuclear resonance fluorescence (NRF) experiment with L0289001 41 quasimonochromatic linearly polarized photon beams L0289001 42 below particle separation thresholds. The measured L0289001 43 experimental average cross sections sigmaexp are the L0289001 44 sum of nonresonant elastic scattering processes and L0289001 45 NRF processes. L0289001 46 ERR-ANALYS (DATA-ERR) No details on sources of uncertainties. L0289001 47 CORRECTION The correction of the detector response into a single L0289001 48 optimization procedure per energy setting, taking L0289001 49 into account data from all detectors.
