The neutron capture cross section of 59Co has been measured in the energy range from 6 to 200 keV using an 800-ℓ liquid-scintillator detector in conjunction with a pulsed 3-MV Van de Graaff generator as a neutron source. The excellent time resolution of the system, full width of 2.8 nsec at half maximum, permitted derivation of radiation widths for single s-wave resonances to 50-keV neutron energy. Average radiation widths of 0.564 ± 0.024 eVand 0.486 ± 0.016 eV were found for seven J = 3 resonances and ten J = 4 resonances, respectively. No significant correlation between and Γy was found for either spin state. The Maxwellian-averaged cross section for kT = 30 keV was found to be 38 mb over the region from 0.0253-eV to 200-keV neutron energy.
