Masses and lifetimes for $r$-process nucleosynthesis: FRIB outlook

Published CGS16 (2018)
Nuclear masses and lifetimes are key inputs for calculations of rapid neutron capture ($r$-process) nucleosynthesis. Masses and half-lives for thousands of nuclei from the valley of stability to the neutron drip line are required and only a fraction have been experimentally measured. Here we examine the promis of the Facility for Rare Isotope Beams, now under construction at Michigan State University, to dramatically reduce uncertainties in $r$-process abundance patterns due to uncertain masses and half-lives.
