“…Even though the isospin symmetry breaking (ISB) terms are small parts of the nuclear interaction, effects of the ISB terms for nuclear properties have gotten attention, for example, for isobaric analog states [42,[45][46][47], for isobaric multiplet mass equation and the Okamoto-Nolen-Schiffer anomaly in the mirror nuclei mass difference [48][49][50][51][52][53][54][55], and for superallowed β-decay [56]. The ISB interaction can be divided into two parts, the charge symmetry breaking (CSB) and the charge independence breaking (CIB) interactions [57].…”

“…Finally, it is interesting to note that a peninsula of stability is also found in the 100 Z 120 region [47,57] according to the DRHBc theory. It is also noted that some effects might influence the prediction of stability beyond the drip line, such as the triaxial [51] and high-order deformation [57], dynamical correlations [51,58,59], charge-symmetry breaking [60,61], and Coulomb energy corrections [61,62], which deserve more efforts in the future.…”

The possible bound nuclei beyond the two-neutron drip line in the 50 Z 70 region are investigated by using the deformed relativistic Hartree-Bogoliubov theory in continuum (DRHBc)with the density functional PC-PK1. Bound nuclei beyond the drip line of 56 Ba, 58 Ce, 62 Sm, 64 Gd and 66 Dy are predicted, forming peninsulas of stability in the nuclear landscape. Near these peninsulas, there are several multi-neutron emitters which are stable against two-neutron emission but unstable against multi-neutron emission. The underlying mechanism is investigated by studying the total energy, Fermi surface, quadrupole deformation and single-neutron spectrum in the canonical basis. It is found that the deformation effect is crucial for the peninsulas of stability, and pairing correlations are also essential in specific cases. The dependence on the deformation evolution for the stability against neutron emissions is discussed.

“…This may be caused by the adopted different pairing interactions, i.e., the δ pairing in DRHBc and the separable pairing [121] in TRHB. In addition, the isospin-violating nucleon-nucleon interaction may influence the location of the neutron drip line as well [122,123].…”

Ground-state properties of even-even nuclei with 8 ≤ Z ≤ 120 from the proton drip line to the neutron drip line have been investigated using the deformed relativistic Hartree-Bogoliubov theory in continuum (DRHBc) with the density functional PC-PK1. With the effects of deformation and continuum included simultaneously, 2583 even-even nuclei are predicted to be bound. The calculated binding energies, two-nucleon separation energies, root-mean-square (rms) radii of neutron, proton, matter, and charge distributions, quadrupole deformations, and neutron and proton Fermi surfaces are tabulated and compared with available experimental data. The rms deviation from the 637 mass data is 1.518 MeV, providing one of the best microscopic descriptions for nuclear masses. The drip lines obtained from DRHBc calculations are compared with other calculations, including the spherical relativistic continuum Hartree-Bogoliubov (RCHB) and triaxial relativistic Hartree-Bogoliubov (TRHB) calculations with PC-PK1. The deformation and continuum effects on the limits of the nuclear landscape are discussed. Possible peninsulas consisting of bound nuclei beyond the two-neutron drip line are predicted. The systematics of the two-nucleon separation energies, two-nucleon gaps, rms radii, quadrupole deformations, potential energy curves, neutron densities, neutron mean-field potentials, and pairing energies in the DRHBc calculations are also discussed. In addition, the α decay energies extracted are in good agreement with available data.
