SEMINAR    Thursday February 22nd, 2007 - h. 15:00 Auditorium B. Touschek   W. Greiner (Frankfurt Institute for Advanced Studies, J.W. Goethe-Universität)   Superheavy Elements and Beyond Abstract The status of theory and experiments on Superheavy Nuclei is reviewed. Based with the Two-Center Shell Model, Potential Energy Surfaces are calculated. Fusion, fission, quasifission and other processes are discussed. The experimental advances are reported. In particular time-delay during the formation of giant quasi atoms/molecules will be crucial for observing the change of the Dirac vacuum in supercritical Coulomb fields by spontaneous positron emission. It will be shown how the various phenomena are interrelated.
