M068900100009 REFERENCE (J,PR/C,73,044611,2006) M068900100010 INSTITUTE (2UK EDG,2UK GLS,2SWDLND) M068900100011 FACILITY (MICRT,2SWDLND) M068900100012 INC-SOURCE (TAGD) Tagged photon facility at the MAX-lab, M068900100013 University of Lund. M068900100014 SAMPLE Target was a 100x100 mm rigid graphite slate (99.5 % M068900100015 purity) of physical thickness ~ 2.5 mm (562.5 M068900100016 mg/cm**2). M068900100017 DETECTOR (TELES,SOLST,HPGE) Solid-state detector telescope M068900100018 which comprised two DSSSDs (double-sided Si strip M068900100019 delta-E detector) and HpGe detector, which measured M068900100020 proton emission angle and energies, respectively. M068900100021 (HPGE) Coaxial HpGe detector that had a relative peak M068900100022 efficiency of 70 % for the detection of 1.33 MeV M068900100023 gamma-rays, placed with the front face 70 mm from M068900100024 the target at an angle of 95 degree to the beam M068900100025 direction and subtended a solid angle of ~ 700 msr. M068900100026 METHOD (COINC,EDE,GSPEC) Decay gamma-spectra measurements in M068900100027 coincidence with reaction photoprotons. M068900100028 CORRECTION Energy spectra Doppler-shift correction. M068900100029 ANALYSIS Final corrected deexcitation gamma-ray spectrum was M068900100030 unfolded using the responce functions for all M068900100031 gamma-lines to produce the final fit, from which M068900100032 the number of counts included in each full-energy M068900100033 peak was determined. M068900100034 ERR-ANALYS (DATA-ERR) No information on the sources of M068900100035 uncertainties. M068900100036 COMMENT Relative population of states in 11B following the M068900100037 12C(g,p)11B reaction have been measured with high M068900100038 resolution using 70 % HpGe gamma-detector to observe M068900100039 decay gamma-rays from the residual nucleus. The M068900100040 triplet of states near 7 MeV in 11B are resolved and M068900100041 measured populations compared to previous data. The M068900100042 analysis includes a consideration of gamma-proton M068900100043 angular correlations, which was not made in the M068900100044 previous measurement. The new and previous results M068900100045 corrected for angular correlation effects agree M068900100046 reasonably well with calculatons that include one- M068900100047 and two-body nuclear currents, pion exchange, and M068900100048 DELTA currents, under the assumption that the M068900100049 photons are mainly absorbed on exchanged pions.
