TY - JOUR A1 - Soff, Gerhard A1 - Oberacker, Volker A1 - Greiner, Walter T1 - Inner-shell ionization induced by nuclear Coulomb excitation in collisions of very heavy ions T2 - Physical review letters N2 - K- and L-shell ionization of 238U with Xe and U projectiles is investigated. Internal conversion following nuclear Coulomb excitation which is particularly important for deformed heavy nuclei is compared with direct ionization of inner-shell electrons in superheavy quasimolecules. Both processes exhibit different impact-parameter dependences. As a result of internal conversion, about 0.1-0.3 K holes per central collision are created.
