M052800100012 INC-SOURCE (QMPH,TAGD) Electron tagged bremsstrahlung. M052800100013 DETECTOR (SCIN) NEA2132A Liquid scintillator. M052800100014 METHOD (TOF) Time-of-flight spectrometer consisted of 2 M052800100015 scintillators. M052800100016 ANALYSIS (SHAPE) Pulse shape analysis distinguished neutron M052800100017 signals from electromagnetic background and charged M052800100018 particles. M052800100019 ERR-ANALYS (ERR-S) Statistical uncertainties, which include M052800100020 uncertainties arising from the four gaussian fiting M052800100021 procedure used to extract the peak areas are M052800100022 presented. M052800100023 (ERR-SYS) Systematic uncertainties are estimated to be M052800100024 20 %. M052800100025 COMMENT High resolution measurements of the reaction C-12(g,n) M052800100026 at eg about 58 MeV are presented. The distribution of M052800100027 strength to the resolved bound final states in C-12 M052800100028 is compared with that of B-11 obtained in previous M052800100029 analogous (g,p) measurements and the implications for M052800100030 the theoretical description of (g,n) reactions are M052800100031 discussed. these new results confirm the importance M052800100032 of two-nucleon effects in intermediate energy photon M052800100033 absorption and highlight inadequacies in M052800100034 state-of-the-art mucroscopic calculations of (g,n) M052800100035 reactions.
