The cross section for the ~(93)Nb(n,2n)~(92g)Nb reaction is measured by activation method. The experimental result is 1355±149 mb at the neutron energy of 14.6±0.3 MeV. And the excitation curve of ~(93)Nb(n,2n)~(92g)Nb reaction is calculated by using HFTT program in neutron energy range from 9 MeV to 16 MeV.
