Self-Consistent Study of the Ground State and $$\beta$$ -Decay Properties of Oxygen and Fluorine Isotopes

For neutron-rich O and F isotopes in the region of the so-called oxygen anomaly, the one- and two-neutron separation energies, charge and matter radii are calculated within the Fayans energy density functional DF3-a. The beta-decay half-lives and delayed multi-neutron emission branchings are treated in the Continuum Quasiparticle Random Phase approximation (DF3-a $$+$$ CQRPA). We discuss the applicability limits of the global approaches for the ground state and integral $$\beta$$ -decay properties of light nuclei. These characteristics calculated within the DF3-a $$+$$ CQRPA and relativistic RHB $$+$$ RQRPA are compared for oxygen and fluorine isotopic chains.
