    "abstract": "The analysis of quasiparticle spectra in heaviest $A\\sim 250$ nuclei with\nspectroscopic data provides an additional constraint for the choice of\neffective interaction for the description of superheavy nuclei. It strongly\nsuggest that only the parametrizations of the relativistic mean field\nLagrangian which predict Z=120 and N=172 as shell closures are reliable for\nsuperheavy nuclei. The influence of the central depression in the density\ndistribution of spherical superheavy nuclei on the shell structure is studied.\nLarge central depression produces large shell gaps at Z=120 and N=172. The\nshell gaps at Z=126 and N=184 are favored by a flat density distribution in the\ncentral part of nucleus. It is shown that approximate particle number\nprojection (PNP) by means of the Lipkin-Nogami method removes pairing collapse\nseen at these gaps in the calculations without PNP.",
