Measurement of neutron radiative capture in cobalt-59. [6 to 200 keV, cross section, J, resonance]
The neutron capture cross section of /sup 59/Co was 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 eV and 0.486 +- 0.016 eV were found for seven J = 3 resonances and ten J = 4 resonances, respectively. No significant correlation between GAMMA/sup 0//sub n/ and GAMMA/sub ..gamma../ 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.
