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 $\alpha$-decay energies and proton emitters based on the RCHB calculations are investigated.

原子核的基态性质 $8⩽ž⩽120$从球质子滴线到中子滴线，已经使用相对论密度泛函PC-PK1进行了球相对论连续性哈特里-波哥利布波夫（RCHB）理论研究。加上连续体的影响，预计总共将束缚9035个核，这大大扩展了用其他方法预测的现有核景观。将计算出的结合能，分离能，中子和质子费米表面，中子，质子，物质和电荷分布的均方根（rms）半径，基态自旋和奇偶性制成表格。与没有配对相关性的相对论平均场计算以及其他预测地形相比，详细讨论了用RCHB获得的核态势的扩展，特别是对于富中子侧。已发现，由于配对相关性，结合态与连续体之间的耦合在扩展核景观方面起着至关重要的作用。还讨论了RCHB计算的分离能，半径，密度，电势和配对能的系统。除此之外$\alpha$研究了基于RCHB计算的衰变能量和质子发射体。
