The uncertainties in the 22Ne + α-capture reactions and magnesium production in intermediate-mass AGB stars Original Research Article

We study how the production of the neutron-rich magnesium isotopes in intermediate mass Asymptotic Giant Branch stars is affected by uncertainties in the neutron-capture reactions involving the Mg isotopes and uncertainties in the 22Ne + α-capture reaction rates. We also examine how uncertainties in these rates affect the stellar yields of species from 22Ne through to 31P, which is important for chemical evolution models.
