Extension of the nuclear landscape to hyperheavy nuclei

Abstract: The properties of hyperheavy nuclei and the extension of nuclear landscape to hyperheavy nuclei are extensively studied within covariant density functional theory. Axial reflection symmetric and reflection asymmetric relativistic Hartree-Bogoliubov (RHB) calculations are carried out. The role of triaxiality is studied within triaxial RHB and triaxial relativistic mean field + BCS frameworks. With increasing proton number beyond Z ∼ 130 the transition from ellipsoidal-like nuclear shapes to toroidal ones takes … Show more

“…Combined with the results obtained previously in Ref. [1] for a non-linear meson exchange model, these results indicate that parametric correlations exist in all major classes of CDFTs when the functionals are fitted to the ground state properties of finite nuclei and to nuclear matter properties. In particular, for the density dependence in the isoscalar channel only one parameter is really independent.…”

“…As shown in Ref. [1] these correlations between the model parameters are visible even for higher values of ∆χ 2 max . Thus, we use ∆χ 2 max = 3.0 for the DDME-X and PC-X functionals.…”
