Beta decay of deformed r-process nuclei near A = 80 and A= 160, including odd-A and odd-odd nuclei, with the Skyrme finite-amplitude method
T. Shafer, J. Engel, C. Fröhlich +3
After identifying the nuclei in the regions near A =80 and A = 160 for which beta-decay rates have the greatest effect on weak and main r-process abundance patterns, we apply the f…
The impact of nuclear masses near on -process abundances
M. Mumpower, D. -L. Fang, R. Surman +2
We have performed for the first time a complete -process mass sensitivity study in the region. We take into account how an uncertainty in a single nuclear mass propagates…
The sensitivity of r-process nucleosynthesis to the properties of neutron-rich nuclei
R. Surman, M. Mumpower, J. Cass +1
About half of the heavy elements in the Solar System were created by rapid neutron capture, or r-process, nucleosynthesis. In the r-process, heavy elements are built up via a seque…
The Rare Earth Peak : An Overlooked r-Process Diagnostic
M. Mumpower, G. McLaughlin, R. Surman
The astrophysical site or sites responsible for the r-process of nucleosynthesis still remains an enigma. Since the rare earth region is formed in the latter stages of the r-proces…
Nuclear masses near that influence -process abundances
M. Mumpower, R. Surman, M. Beard +2
Nuclear masses are one of the key ingredients of nuclear physics that go into astrophysical simulations of the process. Nuclear masses effect -process abundances by entering…
Horizons: Nuclear Astrophysics in the 2020s and Beyond
H. Schatz, A. D. Becerril Reyes, A. Best +162
Nuclear Astrophysics is a field at the intersection of nuclear physics and astrophysics, which seeks to understand the nuclear engines of astronomical objects and the origin of the…
Neutron capture rates and r-process nucleosynthesis
R. Surman, M. Mumpower, G. C. McLaughlin +3
Simulations of r-process nucleosynthesis require nuclear physics information for thousands of neutron-rich nuclear species from the line of stability to the neutron drip line. Whil…
Sensitivity studies for r-process nucleosynthesis in three astrophysical scenarios
R. Surman, M. Mumpower, J. Cass +3
In rapid neutron capture, or r-process, nucleosynthesis, heavy elements are built up via a sequence of neutron captures and beta decays that involves thousands of nuclei far from s…
Low-Energy Magnetic Radiation
S. Frauendorf, M. Beard, M. Mumpower +2
A pronounced spike at low energy in the strength function for magnetic radiation (LEMAR) is found by means of Shell Model calculations, which explains the experimentally observed e…
The impact of global nuclear mass model uncertainties on -process abundance predictions
M. Mumpower, R. Surman, A. Aprahamian
Rapid neutron capture or `-process' nucleosynthesis may be responsible for half the production of heavy elements above iron on the periodic table. Masses are one of the most imp…
