Recent experimental results have confirmed a possible reduction in the GT$_+$ strengths of pf-shell nuclei. These proton-rich nuclei are of relevance in the deflagration and explosive burning phases of Type Ia supernovae. While prior GT strengths result in nucleosynthesis predictions with a lower-than-expected electron fraction, a reduction in the GT$_+$ strength can result in an slightly increased electron fraction compared to previous shell model predictions, though the enhancement is not as… Expand
Electron-capture rates of nuclei at stellar environments and nucleosynthesis
Electron-capture rates in nuclei at stellar environments are evaluated by using new shell-model Hamiltonians. A new Hamiltonian for pf-shell, GXPF1J, can describe Gamow-Teller (GT) strengths in NiExpand
