Isobaric resonances, beta decay and delayed multineutron emission in very neutron-rich nuclei
Abstract
The isobaric-analog resonancesfor nuclei around the neutron shell closures at N = 20, 50, 82 are treated in thefullyself-consistentDensityFunctionalplusContinuumQuasiparticleRandomPhaseApproximation (DF+CQRPA).The aim is to check how the self-consistency is preserved in the calculations for long isotopic chains. The beta-decay half-lives and delayed multi-neutron emission branchingare calculated for the reference Ni isotopic chain. The relative contributions of the GT and first-forbidden transitions are compared with that of the relativistic QRPA and Finite Amplitude Method. The accuracy of the global beta decay calculations performed within FRDM+RPA, DF+CQRPA and RHB+QRPA models are analysed.
