Abstract

Abstract: We study the s -process abundances at the epoch of the Solar-system formation as the outcome of nucleosynthesis occurring in AGB stars of various masses and metallicities. The calculations have been performed with the Galactic chemical evolution (GCE) model presented by [1, 2]. With respect to previous works, we used updated solar meteoritic abundances, a neutron capture cross section network that includes the most recent measurements, and we implemented the s -process yields with an extended range of AGB initial masses. The new set of AGB yields includes a new evaluation of the 22 Ne(α, n) 25 Mg rate, which takes into account the most recent experimental information.
