M055400100003 AUTHOR (F.De Smet,H.Ferdinande,R.Van de Vyver, M055400100004 L.Van Hoorebeke,D.Ryckbosch,C.Van den Abeele, M055400100005 J.Dias,J.Ryckebusch) M055400100006 REFERENCE (J,PR/C,47,652,1993) M055400100007 INSTITUTE (2BLGGHT) M055400100008 FACILITY (LINAC,2BLGGHT) The Gent University 90 MeV electron M055400100009 linear accelerator with duty factor of 0.1 %. M055400100010 INC-SOURCE (BRST) M055400100011 METHOD (EDE) M055400100012 DETECTOR (TELES,SILI,HPGE) Each of three telescopes consisted M055400100013 of a thin (500 or 600 micron) Si transmission M055400100014 dE-detector and LN-cooled thick (10 or 20 mm) HPGe M055400100015 stopping E-detector. M055400100016 SAMPLE A beryllium oxide ceramic sheet with a thickness of M055400100017 82.65 mg/cm2 or 151.1 mg/cm2. M055400100018 ANALYSIS (DIFFR) The angular distributions for the protons M055400100019 leaving the final nucleus in the ground state were M055400100020 extracted from the tip region of the photoproton M055400100021 energy spectra. M055400100022 FLAG (1.) Target thickness was 82.65 mg/cm2 M055400100023 (2.) Target thickness was 151.1 mg/cm2 M055400100024 ERR-ANALYS (ERR-S) Statistical errors (from 5 to 10% for the M055400100025 forward and from 5 up to more than 20% for the M055400100026 backward angles) M055400100027 (ERR-SYS) Systematic uncertainties were estimated to M055400100028 be about 15% and stems from several contributions: M055400100029 the energy calibration of the detectors (due to M055400100030 extrapolation), the effect on the cross section M055400100031 due to the error in the determination of the M055400100032 end-point energy, the calibration constant of the M055400100033 monitoring device, and the target thickness M055400100034 homogeneity. M055400100035 COMMENT The differential cross section for the M055400100036 160(gamma,p0)15N reaction has been investigated at M055400100037 photon energies Eg between 33 and 69 MeV using a M055400100038 bremsstrahlung beam; angular distributions at M055400100039 laboratory angles of 30, 45, 60, 75, 90, and 120 M055400100040 degree were extracted from the tip region of the M055400100041 photoproton spectra when stepping the end-point in M055400100042 4 MeV intervals. The data were compared with M055400100043 calculations based on a self-consistent microscopic M055400100044 approach.
