Cross section measurements of the 23Na(n, 2n)22Na, 58Ni(n, 2n)57Ni and 115In(n,n′)115mIn reactions

Abstract Cross sections for two high energy threshold reactions 23 Na( n , 2 n ) 22 Na and 58 Ni( n , 2 n ) 57 Ni were measured by the activation method in the neutron energy range from 14 to 18 MeV. Inelastic scattering cross section for 115 In was measured in the threshold region, i.e. from 0.5 to 1.3 MeV. The results of measurements are compared with scarce and divergent earlier data.
