Ground-state properties of $A=20\mathrm{}$ nuclei ${(}^{20}\mathrm{N},$ ${}^{20}\mathrm{O},$ ${}^{20}\mathrm{F},$ ${}^{20}\mathrm{Ne},$ ${}^{20}\mathrm{Na},$ and ${}^{20}\mathrm{Mg})$ are described in the framework of relativistic Hartree-Bogoliubov theory. The model uses the $\mathrm{NL}3\mathrm{}$ effective interaction in the mean-field Lagrangian, and describes pairing correlations by the pairing part of the finite-range Gogny interaction $D1S.\mathrm{}$ Binding energies, quadrupole deformations, nuclear matter radii, and differences in radii of proton and neutron distributions are compared with recent experimental data.
