O103600300004 PART-DET (N) O103600300005 ERR-ANALYS (ERR-S) The statistical errors for the measurements of O103600300006 neutron rates were below 10% for E(p) approx. 1.45 MeV O103600300007 and better at higher energies. O103600300008 COMMENT -By authors. Because the threshold energy for O103600300009 Au-197(p,n) is equal 1.203-MeV, background O103600300010 neutrons were produced by the target backing. Neutrons O103600300011 produced by the Au-197(p,n) reactions were measured on O103600300012 a gold target over the range more or equal 1.58-MeV andO103600300013 less or equal 2.65-MeV in steps of 100-KeV. When O103600300014 calculating the neutron counting rates from the O103600300015 Cu-65(p,n) reactions, the energy loss of the protons O103600300016 in copper layer was carefully taken into account. SinceO103600300017 the thickness of the copper layer was 320-mug/cm**2, O103600300018 equivalent to an energy loss of roughly 30-KeV, the O103600300019 neutron rates for the Cu-65(p,n)Zn-65 reactions for a O103600300020 particular energy were determined by subtracting the O103600300021 background neutrons from the Au-197(p,n) reactions at O103600300022 30-KeV lower proton energy. The total neutron rates O103600300023 from E-CM less or 2.1-MeV are practically equal to O103600300024 those of the Au-197(p,n) reactions from the gold O103600300025 backing.
