✦ Synopsis

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 22 Ne + α-capture reaction rates. We also examine how uncertainties in these rates affect the stellar yields of species from 22 Ne through to 31 P, which is important for chemical evolution models.
