The limits of the nuclear landscape explored by the relativistic continuum HartreeBogoliubov theory
Abstract
The groundstate properties of nuclei with 8 ⩽ Z ⩽ 120 from the proton drip line to the neutron drip line have been investigated using the spherical relativistic continuum HartreeBogoliubov (RCHB) theory with the relativistic density functional PCPK1. With the effects of the continuum included, there are totally 9035 nuclei predicted to be bound, which largely extends the existing nuclear landscapes predicted with other methods. The calculated binding energies, separation energies, neutron and proton Fermi surfaces, rootmeansquare (rms) radii of neutron, proton, matter, and charge distributions, groundstate spins and parities are tabulated. The extension of the nuclear landscape obtained with RCHB is discussed in detail, in particular for the neutronrich side, in comparison with the relativistic mean field calculations without pairing correlations and also other predicted landscapes. It is found that the coupling between the bound states and the continuum due to the pairing correlations plays an essential role in extending the nuclear landscape. The systematics of the separation energies, radii, densities, potentials and pairing energies of the RCHB calculations are also discussed. In addition, the αdecay energies and proton emitters based on the RCHB calculations are investigated.
