L014300100010 DETECTOR (HPGE,SCIN) High-purity germanium detector with a L014300100011 relative efficiency of 128%. The resolution of the L014300100012 detector is approximately 0.05% in the energy region L014300100013 of interest, significantly smaller than the energy L014300100014 resolution of the beam. The beam monitor was a fast L014300100015 plastic scintillator 3 mm thick. L014300100016 METHOD (TRN,EXTB) The gamma-ray beam was transported L014300100017 approximately 100 m from the electron-photon L014300100018 collision point in vacuum. The gamma-ray beam passes L014300100019 out of the evacuated beam pipe, through a thin L014300100020 crystalline window to be collimated and monitored L014300100021 before passing through the sample and onto the HPGe L014300100022 detector. The beam-energy spread was held to less L014300100023 than 1% FWHM in all cases. L014300100024 ERR-ANALYS (DATA-ERR) No details on sources of uncertainties.
