Abstract
For neutron-rich isotopes in the region of the “oxygen anomaly”, the one- and two-neutron emission thresholds, neutron driplines positions, beta-decay half-lives and delayed multi-neutron emission branchings are calculated based on the Fayans energy density functional plus Continuum Quasiparticle Random Phase approximation. The applicability of the global approaches for treating the ground state and integral β-decay properties in light nuclei are discussed. Performance of the DF3a + CQRPA and relativistic RHB + RQRPA for oxygen isotopic chain is analysed.
