Neutron Capture Cross Section

Procedures are described for (a) the separation by ion exchange chromatography of submicrogram quantities of Ac227 from its daughters and (b) the absolute determination of Ac227 by measurement of the rate of growth of α-particle emission from an initially pure source. These procedures are utilized in the determination of the reactor and thermal neutron capture cross sections and the resonance capture integral of Ac227 by an activation method.Assuming 36.5 barns for the thermal neutron capture cross section of Co59, a value of σ2200 = 814 ± 13 barns has been obtained for Ac227. The resonance capture integral (from 0.5 ev to ∞) was found to be 1177 ± 19 barns relative to 48.6 barns for the resonance capture integral of Co59.

Calorimetric Determination

The half-life of Th230 (ionium) has been measured by a calorimetric method and was found to be 75,200 years with a standard error of ± 1,600 years.In the light of this measurement, previously published values for the 2200 m/sec neutron capture cross section and the resonance capture integral (from 0.5 ev to ∞) of Th230 have been amended to 22.7 ± 0.6 barns and 996 ± 40 barns respectively.

The Mean

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.
