The Uncertainties in the 22Ne + alpha-Capture Reaction Rates and the Production of the Heavy Magnesium Isotopes in Asymptotic Giant Branch Stars of Intermediate Mass

Karakas, Amanda; Lugaro, Maria A; Wiescher, M.; Gorres, J.; Ugalde, C

Description

We present new rates for the 22Ne(α, n) 25Mg and 22Ne(α, γ) 26Mg reactions, with uncertainties that have been considerably reduced compared to previous estimates, and we study how these new rates affect the production of the heavy magnesium isotopes in
