Theoretical evaluation of the reaction rates for 26Al(n,p)26Mg and 26Al(n,α)23Na

The reactions that destroy Al-26 in massive stars have significance in a number of astrophysical contexts. We evaluate the reaction rates of Al-26(n,p) Mg-26 and Al-26(n,alpha) Na-23 using cross sections obtained from the codes EMPIRE and TALYS. These have been compared to the published rates obtained from the NON-SMOKER code and to some experimental data. We show that the results obtained from EMPIRE and TALYS are comparable to those from NON-SMOKER. We also show how the theoretical results vary with respect to changes in the input parameters. Finally, we present recommended rates for these reactions using the available experimental data and our new theoretical results.
