Electron capture processes in intermediate mass stars
(2014) 13th Nuclei in the Cosmos, NIC 2014 In Proceedings of Science 07-11-July-2015.- Abstract
Intermediate mass stars develop a degenerate core constituted of O, Ne and Mg during their evolution. As the density in the core increases electron capture sets in igniting Ne and O burning. Particularly important is electron capture on 20Ne that has been found recently to be dominated by a second forbidden transition from the 0+ ground state of 20Ne to the 2+ ground state of 20F. We have performed shell-model calculations to determine the transition strength and provide an updated value of the electron capture rate and the expected branching ratio to the corresponding β-decay process.
