Abstract :
In addition to numerous problems in the quest of the astrophysical site for the r-process, nuclear physics uncertainties of the r-process modeling are still high. For the β-decay rates predictions, they stem mostly from non self-consistency of the nuclear models. Also, the sole consideration of the allowed β-decay commonly used in large-scale microscopic schemes needs to be revised. The first systematic study of the GT and first-forbidden β-decays near the closed neutron shells at N=50, 82, 126 was performed in the self-consistent EDF+CQRPA approach. The importance of the first-forbidden decays for Z≥50, N≈82 nuclei and near N=126 closed shell is shown.
