Using excitation-energy dependent fission yields to identify key fissioning nuclei in r-process nucleosynthesis
Nicole Vassh, Ramona Vogt, Rebecca Surman +8
We evaluate the impact of using sets of fission yields given by the GEF code for spontaneous (sf), neutron-induced ((n,f)), and beta-delayed (betadf) fission processes which take i…
FRIB and the GW170817 Kilonova
A. Aprahamian, R. Surman, A. Frebel +45
In July 2018 an FRIB Theory Alliance program was held on the implications of GW170817 and its associated kilonova for r-process nucleosynthesis. Topics of discussion included the a…
Actinide Production in Neutron-Rich Ejecta of a Neutron Star Merger
Erika M. Holmbeck, Rebecca Surman, Trevor M. Sprouse +4
The rapid-neutron-capture ("r") process is responsible for synthesizing many of the heavy elements observed in both the solar system and Galactic metal-poor halo stars. Simulations…
Californium-254 and kilonova light curves
Y. Zhu, R. T. Wollaeger, N. Vassh +13
Neutron star mergers offer unique conditions for the creation of the heavy elements and additionally provide a testbed for our understanding of this synthesis known as the -proc…
r-Process Nucleosynthesis: Connecting Rare-Isotope Beam Facilities with the Cosmos
C. J. Horowitz, A. Arcones, B. Côté +35
This is an exciting time for the study of r-process nucleosynthesis. Recently, a neutron star merger GW170817 was observed in extraordinary detail with gravitational waves and elec…
-delayed fission in -process nucleosynthesis
M. R. Mumpower, T. Kawano, T. M. Sprouse +4
We present -delayed neutron emission and -delayed fission calculations for heavy, neutron-rich nuclei using the coupled Quasi-Particle Random Phase Approximation plus Hauser-…
