Abstract / Description of output

We present a study of nucleosynthesis for conditions of high Ye outflows from Neutron Star Mergers (BNSs). We investigate the effect of new beta–decay rates measurements and uncertainties in nuclear masses of the newly measured 84,85Ga to the r–process nucleosynthesis calculations. The impact of these quantities to the production of the elements of the r–process abundance pattern for A<100 is quantified and presented. This proceedings paper is based on [1].
