Direct Neutron Capture inCo59(n, γ)Co60

Abstract
The variation in intensity of 40 individual γ rays produced by neutron capture in cobalt was observed for neutron energies less than 1500 eV. The observed variations were consistent with the existence of a direct component in the radiative capture reaction mechanism. A direct-capture cross section of 9.2±2.4 mb at 1-eV neutron energy was deduced for the 7.492-MeV ground-state transition.
