What is Reevaluation of the 22(α,γ)Mg26 about?
## Background: The competing 22 Ne(α, γ ) 26 Mg and 22 Ne(α, n) 25 Mg reactions control the production of neutrons for the weak s process in massive and asymptotic giant branch (AGB) stars. In both systems, the ratio between the corresponding reaction rates strongly impacts the total neutron budget and strongly influences the final nucleosynthesis. A number of experimental studies have been performed over recent years which necessitate the reevaluation of the 22 Ne(α, γ ) 26 Mg and 22 Ne(α, n) 25 Mg reaction rates. Evaluations of the reaction rates following the collection of new nuclear data presently show differences of up to a factor of 500, resulting in considerable uncertainty in the resulting nucleosynthesis. Purpose: To reevaluate the 22 Ne(α, γ ) 26 Mg and 22 Ne(α, n) 25 Mg reaction rates using updated nuclear data from a number of sources including updating spin and parity assignments. Methods: With updated spin and parity assignments, the levels which can contribute to the reaction rates are identified. The reaction rates are computed using a Monte Carlo method which has been used for previous evaluations of the reaction rates in order to focus solely on the changes due t
