Description
Nuclear β-decay half-lives are basic nuclear physics inputs for rapid neutron-capture process (r-process) simulation. Since r-process path is far from the stability line, the accurate description of β-decay half-lives is important for r-process study. In this talk, I will introduce the improvement of β-decay half-life description by including the deformation degree of freedom and beyond mean-field effect, respectively, based on relativistic density functionals. By the sensitivity study of β-decay half-lives, the most impactful nuclei for r-process rare-earth peak are identified. The impact of β-decay rate of an individual nucleus on the rare-earth peak abundances is analyzed.
