The alpha-decay energies and lifetimes for several alpha-chains of superheavy nuclei were calculated on the basis of Wigner’s mass formula. In this calculation, the contribution of spin–orbit interaction to the nuclear mass is disregarded, in which caseWigner’s spin–isospin symmetry is restored. The calculated alpha-decay energies agree with experimental data better than the results of other modern theoretical approaches. The alpha-decay energies are predicted for several isotopes of charge number Z = 120.
