Abstract

Accurate modeling of $r$-process nucleosynthesis requires reliable calculations for $\ensuremath{\beta}$ decay of nuclei far from stability. The quasiparticle random-phase approximation (QRPA) has been widely used, but deformation and odd numbers of protons and/or neutrons introduce challenges. The authors explain and apply novel advances in the QRPA that address these challenges, providing an enhanced tool for describing astrophysically important decays.
