M056600100004 AUTHOR (A.De Graeve,A.Zieger,R.Van de Vyver,C.Van den Abeele, M056600100005 H.Ferdinande,L.Van Hoorebeke,D.Ryckbosch,F.De Smet, M056600100006 B.Ziegler) M056600100007 REFERENCE (J,FBS,10,37,1991) M056600100008 INSTITUTE (2BLGGHT,2GERMNZ) M056600100009 FACILITY (LINAC,2BLGGHT) The Gent University electron linear M056600100010 accelerator. M056600100011 INC-SOURCE (BRST) M056600100012 METHOD (MAGFR) Magnetic spectrometer. M056600100013 DETECTOR (SI) Large area (2000 mm**2) Si-detector. M056600100014 SAMPLE The targets consisted of CD-2 and CH-2 foils with the M056600100015 total thickness of 4.88 and 4.56 mg/cm**2, M056600100016 respectively. M056600100017 ANALYSIS The cross section values were obtained by comparing M056600100018 the simulated using Monte Carlo simulation M056600100019 photoproton energy distribution with the M056600100020 experimental net spectrum. M056600100021 ERR-ANALYS (ERR-S) Statistical errors. M056600100022 (ERR-SYS) Systematic uncertainties were estimated to M056600100023 be of order of 3 %. M056600100024 COMMENT The forward 2H(gamma,p)n cross section was measured at M056600100025 7.2 and 8.5 MeV photon energy. The new absolute valuesM056600100026 confirm the theoretically predicted presence of a M056600100027 minimum in this cross section. A discrimination was M056600100028 made between the results from various theoretical M056600100029 descriptions.
