The potential energies of heavy and superheavy even-even nuclei were evaluated within the macroscopic-microscopic method using the LSD macroscopic model [1] and the Yukawa-folded mean field potential [2]. The Strutinsky shell correction method [3] and the BCS pairing theory [4] was used to determine the ground state deformation of rotating nuclei. The cranking model [5] was used to evaluate the moments of inertia.
The calculations were performed for even-even Fermi isotopes and heavier nuclei using the modified Funny Hills deformation parameters set [6]. The binding energies, the quadrupole moments and rotational energies of the lowest states evaluated in the equilibrium deformation agree well with the experimental data. The energies of the ground state rotational bands are predicted for all investigated nuclei.
