M045200100003 AUTHOR (T.Chapuran,R.Starr,R.Vodhanel,M.K.Brussel) M045200100004 REFERENCE (J,PR/C,30,54,1984) M045200100005 #doi:10.1103/PhysRevC.30.54 M045200100006 INSTITUTE (1USAUI) M045200100007 FACILITY (MICRT,1USAUI) 100% duty cycle electron accelerator M045200100008 MUSL-2 of University of Illinois. M045200100009 INC-SOURCE (TAGD,BRST) M045200100010 METHOD (EXTB,SITA) M045200100011 SAMPLE 2.4 g/cm**2 target of natural iron (92% Fe-56). M045200100012 DETECTOR (GELI) M045200100013 ANALYSIS (UNFLD) From experimental spectra of scattered M045200100014 photons peak centroids and areas were extracted M045200100015 using the computer program 'sampo'. The centroids M045200100016 were converted to energies using a linear M045200100017 calibration based on five levels (from 2.125 to M045200100018 8.920 MeV) strongly excited in photon scattering M045200100019 from B-11. The scattering yields were converted to M045200100020 cross sections using an empirical determination of M045200100021 the product of incident photon intensity with the M045200100022 detector efficiency. M045200100023 ERR-ANALYS (ERR-S) Statistical errors only. Systematic errors M045200100024 are estimated to be no larger than 8%, arising from M045200100025 uncertainties in the photon flux (5%), geometrical M045200100026 factor (5%), atomic absorption coefficient (3%), and M045200100027 photon energy (1%). M045200100028 COMMENT Resonant photon scattering from Fe-56 has been M045200100029 measured from 5 to 10 MeV using Ge(Li) detector and M045200100030 bremsstrahlung beams with end-point energies of 7.6 M045200100031 and 10.3 MeV. Average elastic and inelastic (to the M045200100032 first excited state) photon scattering cross M045200100033 sections were measured from 5.8 to 11.5 MeV (i.e. to M045200100034 above neutron threshold).
