M051200100004 AUTHOR (E.Kerkhove,P.Berkvens,R.Van De Vyver,D.Declerck, M051200100005 D.Ryckbosch,P.Van Otten,H.Ferdinande,E.Van Camp) M051200100006 INSTITUTE (2BLGGHT) M051200100007 REFERENCE (J,PR/C,29,2061,1984) M051200100008 INC-SOURCE (BRST,HARD) The bremsstrahlung photon beam was M051200100009 hardened by a 19.5 cm thick graphite cylinder, placed M051200100010 about half-way between the Au bremsstrahlung M051200100011 converter target with thickness 90 mg/cm**2 and the M051200100012 reaction chamber. M051200100013 FACILITY (LINAC,2BLGGHT) Ghent State University linac. M051200100014 SAMPLE THE 3.39 MG/CM**2 Thick polystyrene target. M051200100015 METHOD (EXTB,SITA) M051200100016 DETECTOR (SILI) Uncooled solid state detectors with an active M051200100017 area of 200 mm**2 and a thickness of 3 mm. M051200100018 ANALYSIS (DIFFR) Photoprotons were detected at seven angles M051200100019 simultaneously, varying between 37 and 143 degree. M051200100020 The photoproton spectra measured were converted to M051200100021 the differential cross section data. M051200100022 ERR-ANALYS (ERR-S) Statistical errors are given. M051200100023 (ERR-SYS) The total systematic error to be smaller M051200100024 than 12 %. M051200100025 COMMENT The absolute C-12(g,p-0)B-11 reaction cross section M051200100026 was measured in the energy range of the giant dipole M051200100027 resonance. The magnitude of the 90-degree M051200100028 differential cross section, which has an absolute M051200100029 uncertainty of about 12% , is in disagreement with M051200100030 the one obtained by detailed balance from a recent M051200100031 measurements of (p,g-0) reaction cross section, but M051200100032 is in reasonable correspondence with the combined M051200100033 data from Argonne and Stanford groups.
