The Impact

We present a study of nucleosynthesis for conditions of high Ye outflows from NeutronStar Mergers (NSMs). We investigate the effect of new beta-decay rates measurements and uncertaintiesin nuclear masses of the newly measured 84,85 Ga to the r-process nucleosynthesis calculations. The impactof these quantities to the production of the elements of the r-process abundance pattern for A < 100 isquantified and presented.

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 promise 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.
