Differential production cross sections for 63 discrete gamma-rays from 14.9MeV neutron induced 59Co(n,xγ) reactions were measured with a Ge(Le) detector at 30° to 140°. The pulsed-beam time-of-flight technique was employed for background reduction. probable reaction types and transitions of the better part of gamma-ray lines were assigned. Neutron inelastic scattering cross sections for 10 levels and total neutron inelastic scattering cross section of 59Co in 14.9MeV incident neutron energy were obtained.
