Abstract：
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.
