摘要：

Nuclear masses have long been recognized as key nuclear physics inputs for calculations of rapid neutron capture, or r-process, nucleosynthesis. Here, we investigate how uncorrelated uncertainties in nuclear masses translate into uncertainties in the final abundance pattern produced in r-process simulations. These uncertainties can obscure details of the abundance pattern that, in principle, could be used to diagnose the r-process astrophysical site. We additionally examine the impact of reductions of mass uncertainties that will come with new experiments.
