Rotational states in heaviest isotopes

Masses and rotational energies of even-even Fm - Hs isotopes are obtained using the Yukawa-folded single-particle potential and the Lublin Strasbourg Drop . The Strutinsky shell-correction method and the BCS approximation were used to evaluate the shell and pairing corrections. The paring force strength is adjusted to the experimental rotational states of the considered nuclei. The ground-state masses and the lowest rotational states obtained by using the cranking moments of inertia at the equilibrium deformations agree well with the experimental data. (author)
