The outcome of astrophysical events depends critically on the structure and reactions of heavy nuclei. These properties often remain unmeasured, leaving theory to fill in the gaps. I will provide a broad overview of recent theoretical progress in the description of heavy nuclei. I will cover progress in structure and reaction models, the behavior of astrophysically relevant nuclear isomers...

Beta-delayed fission (βDF) is a two-step process where a parent nucleus β-decays into a daughter that fissions [1]. βDF plays a role in the termination of the r-process nucleosyn- thesis [2], and so it is of particular interest in the neutron-rich side of the nuclide chart, where only a few studies have been performed. Aiming at expanding the limited infor- mation in this region, an...

39. 80Ge(d,pγ) measurements at FRIB to inform (n,γ) reaction rates in weak r-process nucleosynthesisMara Grinder (Rutgers University)7/24/24, 11:20 AM
Individual (n,γ) rates become important in the weak r-process near Z=26-34 and N=50 during freeze out from a hot process. The (n,γ) rates for a handful of specific isotopes exhibit notable impacts on final r-process abundance patterns in sensitivity studies [1]. One such nucleus with enhanced sensitivity is 80Ge and is in reach for reaction studies at FRIB. The 80Ge(d,pγ) reaction will be...
