M027900100005 AUTHOR (M.J.Aitken,N.Middlemas) M027900100006 INSTITUTE (2UK OXF) M027900100007 REFERENCE (J,PR,117,1111,1960) M027900100008 SAMPLE A target, consisting of 196.6 mg of Cu-65 (Cu-63 M027900100009 contamination 0.6+-0.08%) on a 0.001-in platinum M027900100010 support M027900100011 METHOD (EXTB,SITA) M027900100012 DETECTOR (BF3) M027900100013 INC-SOURCE (BRST) M027900100014 ERR-ANALYS (ERR-S) Statistical errors are presented. M027900100015 COMMENT The 29-Cu-65(g,3n) reaction has been measured from M027900100016 threshold to 110 MeV. The integrated cross section M027900100017 at 110. MeV is 0.037(0.004) MeV*barn. The consequent M027900100018 error in bremsstrahlung monitoring through ignoring M027900100019 this contribution varies from 0.9% at 40 MeV. To M027900100020 1.4% at 110 MeV.
