Abstract: | During the present Thesis, the role of the nuclear masses in r-process nucleosynthesis calculations have been explored. In order to accomplish this goal, we have computed neutron capture rates in the framework of the statistical model for all relevant nuclei in the r-process regime, to be more specific, nuclei ranging from Zn (Z=30) to Bi (Z=83) and contained inside the model dependent driplines. We have use the currently available mass models that best reproduce the known masses with a root mean square deviation smaller than RMSD<600 keV. This include the following set of mass models: Finite Range Droplet Model (FRDM), Weizsäcker-Skyrme model (WS3) and two variants of the Duflo-Zuker mass model, namely DZ10 and DZ31. The thermodynamical conditions were taken from hydrodynamical simulations corresponding to high entropy neutrino winds from core collapse supernovae (SNe) and Neutron star mergers(NSM). |
