Beta-delayed neutron-emission probabilities of neutron-rich S to K isotopes are calculated with nuclear-structure effects taken into account. These results strongly affect predictions made in high-neutron-density astrophysical scenarios for isotopic abundances of several elements. In particular, it is demonstrated that the solar abundance ratio Ca-48/Ca-46 as well as the correlated Ca and Ti isotopic anomalies can be explained by the same nucleosynthesis process.
