Measurement of Cross Sections for 185Re(n,2n) 184g,mRe and 191Ir(n,2n)190Ir Reactions by 14 MeV Neutrons

  • The cross sections of 185Re(n,2n) 184gRe,185Re(n,2n)184mRe and 191Ir(n,2n) 190Ir reactions induced by 14.7MeV neutrons were measured by the activation method. The experimental results for the reactions are (1817±85)mb,(390±18)mb and (2038±82)mb, respectively. And the excitation curves of these reactions were calculated by using the code HFTT in neutron energy range from 7 MeV to 18 MeV.
