The Stability

We calculate the ground state properties of recently synthesized superheavy elements (SHEs) from Z = 105–118 along with the predicted proton magic Z = 120. The relativistic and nonrelativistic mean field formalisms are used to evaluate the binding energy (BE), charge radius, quadrupole deformation parameter and the density distribution of nucleons. We analyzed the stability of the nuclei based on BE and neutron to proton ratio. We also studied the bubble structure which reveals the special features of the superheavy nuclei.

Ground State Properties

We have investigated the ground-state properties of odd-Z superheavy isotopes with even neutron numbers in previous article (Phys. Rev. C67 064302 (2003)). In this work we extend the previous researches to the ground-state properties of odd-Z isotopic chains with odd neutron numbers. This covers the isotopic chains with Z = 109 - 115 which are current interests of experiments. The ground state properties of these odd-Z superheavy nuclei have been systematically calculated by deformed relativistic mean-field model (RMF) with two sets of force parameters TMA and NL-Z2. The theoretical results from the RMF model are compared with those from the Skyrme-Hartree-Fock model (SHF). The binding energies of two models are in good agreement with each other, but the quadrupole deformations show model dependence in some mass regions. The alpha decay energies from the two theoretical models are also compared with recent experimental data, which include three alpha decay chains of superheavy elements 115 and 113. The reasonable agreement shows the validity of the self-consistent mean-field models for superheavy mass region.
