sup(26g,m)Al production cross sections from the 23Na(α,n)26Al reaction

Cross sections have been determined for the production of sup(26g,m)Al from the 23Na(α, n) reaction. Total 26Al production cross sections were obtained from measurements of the thick-target neutron yield. sup(26m)Al cross sections were measured using an activation technique. sup(26g)Al cross sections were deduced by subtracting the sup(26m)Al cross sections from the total (α, n) cross sections. The principle of detailed balance has been applied to the low-energy data to obtain cross sections for the astrophysically interesting sup(26g)Al(n, α0)23Na reaction. These results are compared with the results of Hauser-Feshbach calculations. (orig.)
