摘要

The occurrence of the spherical shell closures in superheavy nuclear systems is explored within the relativistic Hartree-Fock-Bogoliubov (RHFB) theory with densitydependent meson-nucleon couplings. We use the two-nucleon gaps δ_(2n(p)) and pairing gaps ?_v(π) to characterize the shell effects. The results depend slightly on the forces used, but the general set of magic numbers beyond ~(208)Pb are Z = 120, 138 and N = 172, 184, 228 and 258. Our calculations are in favor of the nuclide ~(304)120 as the next spherical doubly magic nucleus. Combined with the bulk properties of symmetric matter, we find that the shell effects are sensitive to the values of both scalar mass and effective mass. These two masses essentially determine the spin-orbit splittings and single-particle level density, respectively. Furthermore, the breaking of relativistic pseudo-spin symmetry influences the level structure and the occurrence of closed shells.
