Abstract.A proper treatment of the resonant continuum is to take account of not only the energy of the resonant state, but also its width. The effect of resonant states on pairing correlations is presented in the framework of the relativistic mean-field theory plus Bardeen-Cooper-Schrieffer (BCS) approximation with a constant pairing strength. The study is performed in an effective Lagrangian with the parameter set NL3 for neutron-rich even-even Ni isotopes. Results show that the contribution…

Microscopic self-consistent study of neon halos with resonant contributions
Recent reaction measurements have been interpreted as evidence of a halo structure in the exotic neutron-rich isotopes Ne-29,Ne-31. While theoretical studies of Ne-31 generally agree on its halo
