M051400100004 AUTHOR (R.Van De Vyver,J.Devos,H.Ferdinande,R.Carchon, M051400100005 E.Van Camp) M051400100006 INSTITUTE (2BLGGHT) M051400100007 REFERENCE (J,ZP/A,284,91,1978) M051400100008 INC-SOURCE (BRST) M051400100009 FACILITY (LINAC,2BLGGHT) Ghent State University linac. M051400100010 SAMPLE The lead target, containing 91 % of Pb-208 and 7 % of M051400100011 Pb-207, had a thickness of 4.38 g/cm**2 for M051400100012 messurements in the energy region from 8 to 10.5 MeV M051400100013 and of 2.17 g/cm**2 above 10.5 MeV. M051400100014 METHOD (EXTB,SITA) The reaction yield curve measurement. M051400100015 DETECTOR (BF3) 4PI Halpern-type detector. M051400100016 ANALYSIS (PLA) The yield curve has been analysed using the M051400100017 variable bin Penfold-Leiss method for cross section M051400100018 unfolding together with the Thies's criterion for M051400100019 decorrelation of the cross section errors. M051400100020 REL-REF (N,,D.M.Crawford+,J,NIM,109,573,1973) The Thies's M051400100021 criterion. M051400100022 (N,,L.I.Schiff,J,PR,83,252,1951) The Schiff's M051400100023 integrated-over-angles bremsstrahlung spectral shape. M051400100024 ERR-ANALYS (DATA-ERR) Mean-root-squared uncertainties. M051400100025 COMMENT The total photoneutron cross section of Pb-208 was M051400100026 measured between 8 and 13 MeV using the M051400100027 bremsstrahlung photon facility from 35 MeV linac. M051400100028 Considerable resonance structure was observed in the M051400100029 cross section, of which the peak around 9 MeV, as M051400100030 well as the structure around 10.8 mev may be due to M051400100031 E2 excitations.
