Abstract
A determination of the neutron capture cross section of Co59 leading to the excited state of Co60 has been made by the activation method. Samples of cobalt were irradiated in the center of the Chalk River nuclear reactor in a pure iron capsule using a pneumatic delivery device. The cobalt activity was counted in a windowless counter and compared with the activity of a strip of pure gold irradiated under identical conditions in the same container. The cobalt and gold were counted with and without cadmium wrapping and the contribution due to epicadmium neutrons allowed for in the calculation. The mean value obtained was 18.3 ± 1.7 barns relative to σAu197 = 93 barns.Keywords
