Title: $β$ -decay half-lives of 55 neutron-rich isotopes beyond the $N = 82$ shell gap

Abstract

The $β$ -decay half-lives of 55 neutron-rich nuclei ${}_{134 - 139}{Sn}$ , ${}_{134 - 142}{Sb}$ , ${}_{137 - 144}{Te}$ , ${}_{140 - 146}I$ , ${}_{142 - 148}{Xe}$ , ${}_{145 - 151}{Cs}$ , ${}_{148 - 153}{Ba}$ , and ${}_{151 - 155}{La}$ were measured at the Radioactive Isotope Beam Factory employing the projectile fission fragments of ${}_{238}U$ . The nuclear level structure, which relates to deformation, has a large effect on the half-lives. The impact of newly measured half-lives on modeling the astrophysical origin of the heavy elements is studied in the context of $r$ process nucleosynthesis. For a wide variety of astrophysical conditions, including those in which fission recycling occurs, the half-lives have an important local impact on the second ( $A$ $\approx$ 130) peak.
