The scattering of slow neutrons by cobalt

Abstract

Different techniques have been used to determine with slow neutrons the coherent scattering amplitude bc and the total scattering cross-section σsc of Co. We found values for the bound atom bc=2.78+0.04 fm and for the free nucleus σsc=5.95+0.05 barns.From these quantities, the spin state scattering amplitudes b+ and b corresponding to the compound nucleus states of spin I+1/2 or I−1/2 have been determined as b+=−2.78±0.04 fm and b=+9.91±0.06 fm. These results are not in agreement with previous data, but they are found to be consistent with data obtained from resonance parameters.
