ABSTRACT An extensive theoretical search for the proton magic number in the superheavy
valley beyond $Z=$82 and corresponding neutron magic number after $N=$126 is
carried out. For this we scanned a wide range of elements $Z=112-130$ and their
isotopes. The well established non-relativistic Skryme-Hartree-Fock and
Relativistic Mean Field formalisms with various force parameters are used.
Based on the calculated systematics of pairing gap, two neutron separation
energy and the shell correction energy for these nuclei, we find $Z=$120 as the
next proton magic and N=172, 182/184, 208 and 258 the subsequent neutron magic
numbers.

    ABSTRACT: The ground state and first intrinsic excited state of superheavy nuclei with Z = 120 and N = 160–204 are investigated using both nonrelativistic Skyrme–Hartree–Fock (SHF) and the axially deformed relativistic mean field (RMF) formalisms. We employ a simple BCS pairing approach for calculating the energy contribution from pairing interaction. The results for isotopic chain of binding energy (BE), quadrupole deformation parameter, two neutron separation energies and some other observables are compared with the finite range droplet model (FRDM) and some recent macroscopic–microscopic calculations. We predict superdeformed ground state solutions for almost all the isotopes. Considering the possibility of magic neutron number, two different modes of α-decay chains 292120 and 304120 are also studied within these frameworks. The Qα-values and the half-life for these two different modes of decay chains are compared with FRDM and recent macroscopic–microscopic calculations. The calculation is extended for the α-decay chains of 292120 and 304120 from their excited state configuration to respective configuration, which predicts long half-life (in seconds).

    ABSTRACT: We calculate the ground state properties of recently synthesized superheavy nuclei starting from $Z$=105-120. The nonrelativistic and relativistic mean field formalisms is used to evaluate the binding energy, charge radius, quadrupole deformation parameter and the density distribution of nucleons. We analyzed the stability of the nuclei based on the binding energy and neutron to proton ratio. We also studied the bubble structure of the nucleus which reveals about the special features of the superheavy nucleus.
