Abstract. We present nuclear mass table in the framework of relativistic continuum Hartree-Bogoliubov (RCHB) theory which properly treats pairing correlations in the presence of the continuum. We study the nuclear mass table mainly with spherical symmetry using the density functional PC-PK1. We then briefly discuss on-going calculations for deformed nuclei with axial symmetry in the framework of deformed RCHB theory.

“…They are the extremely neutron-rich nuclei predicted by RCHB, and many of them lie even beyond the neutron drip lines predicted by the other nuclear mass models. For these weakly bound nuclei, as the neutron Fermi surface is close to the continuum threshold, pairing correlations could scatter the nucleons from bound states to the continuum, thus provide a significant coupling between the continuum and bound states [73]. The RCHB theory allows a proper treatment of the continuum and the coupling to the bound states, so it predicts a more extended neutron drip line than the other models.…”

The ground-state 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 Hartree-Bogoliubov (RCHB) theory with the relativistic density functional PC-PK1. 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, root-mean-square (rms) radii of neutron, proton, matter, and charge distributions, ground-state spins and parities are tabulated. The extension of the nuclear landscape obtained with RCHB is discussed in detail, in particular for the neutron-rich 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 α-decay energies and proton emitters based on the RCHB calculations are investigated.

The correlations between the shape of rapidity distribution of the yield of light charged particles and the fragmentation modes in semi-peripheral collisions for 70 Zn+ 70 Zn, 64 Zn+ 64 Zn and 64 Ni+ 64 Ni at the beam energy of 35MeV/nucleon are investigated based on ImQMD05 code. Our studies show there is interplay between the binary, ternary and multi-fragmentation breakup modes. The binary and ternary break-up modes more prefer to emit light charged particles at middle rapidity and give larger values of R mid yield compared with the multi-fragmentation break-up mode does. The reduced rapidity distribution for the normalized yields of p, d, t, 3 He, 4 He and 6 He and the corresponding values of R mid yield can be used to estimate the probability of multi-fragmentation break-up modes. By comparing to experimental data, our results illustrate that ≥40% of the collisions events belong to the multi-fragmentation break-up mode for the reaction we studied.Fragmentation mechanism, i.e. does a nucleus break up into several intermediate mass fragments (IMFs) in intermediate energy heavy ion collisions (HICs) in a statistical (thermal) way or dynamical way, has been a longstanding problem in nuclear physics, and it has attracted a lot of theoretical
