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

Abstract

Cross sections have been determined for the production of 26g, mAl from the 23Na(α, n) reaction. Total 26Al production cross sections were obtained from measurements of the thick-target neutron yield. 26mAl cross sections were measured using an activation technique. 26gAl cross sections were deduced by subtracting the 26mAl 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 26gAl(n, α 0) 23Na reaction. These results are compared with the results of Hauser-Feshbach calculations.
