Strong electric fields of superheavy quasimolecules

The theoretical description of electronic excitations in heavy ion collisions using the adiabatic picture is discussed. The formalism is extended to include supercritical collisions where the 1s level enters the lower continuum. Numerical results on the creation of inner shell vacancies, delta electrons and positrons in various collision systems are discussed. The influence of time delayed nuclear reactions on electronic excitation processes and with the suggestion to use delta electrons as an 'atomic clock' is dealed with. The paper is finished by the more theoretical subject of pointlike particles with charge Zα > 1
