Phenomenological Approach to Extrapolation of Nuclear Binding Energies for Superheavy Elements

We consider the possibility for using the method of local mass relations in the region of superheavy elements with nuclear charge Z > 106. Binding energies, α-decay energies, and half-lives of α-decay are found for isotopes Z = 107–110 and N = 152–161, using formulas for estimating residual np-interaction.
