Systematic Investigations of Binding Energies of Inner-Shell Electrons in Superheavy Quasimolecules

Electronic binding energies in superheavy quasimolecules are calculated using the monopole approximation, finite size and screening effects are included. The validity of the monopole approximation is discussed. A phenomenological description of the binding energy as a function of the total charge (Z1+Z2) and the two-center separationRis given. It is shown, that the 1sσ-ionization rate does not depend on the projectile or target charge, but only on the total charge of the superheavy quasimolecule.
