TY - JOUR A1 - Soff, Gerhard A1 - Müller, Berndt A1 - Greiner, Walter T1 - Spectroscopy of electronic states in superheavy quasimolecules T2 - Physical review letters N2 - We show that information about quasimolecular electronic binding energies in transient atomic systems of Z=Z1+Z2 up to 184 can be obtained from three sources: (1) the impact-parameter dependence of the ionization probability; (2) the ionization probability in head-on collisions as a function of total nuclear charge Z; (3) the delta-electron spectrum in coincidence with K-vacancy formation in asymmetric collisions. Experiments are proposed and discussed.
