Fig. 6. The angular distributions for nat Ni neutron spectra at 18 MeV<br />

4. Conclusion<br />

Neutron-induced reactions on natural nickel have been studied using TALYS at the incident energy<br />

14 MeV and 18 MeV. The neutron-induced differential cross sections have been compared with the<br />

available experimental data. Our calculations are in reasonable agreements with the measured data<br />

through adjusting the transition rates with the energy-dependent matrix elements at 14 MeV but show<br />

some discrepancies at 18 MeV. The Multistep direct/compound model showed similar under<br />

estimations for the emitted angle-dependent neutron spectra and larger discrepancies as incident<br />

neutron energies increase.<br />
