Fusion of heavy nuclei for the formation of superheavy elements — •Alexis Diaz-Torres^1,2, Carsten Greiner¹, Walter Greiner¹, and Werner Scheid² — ¹Institut für Theoretische Physik der Johann Wolfgang Goethe-Universität Frankfurt, Robert Mayer 10, D-60064 Frankfurt am Main, Germany — ²Institut für Theoretische Physik der Justus-Liebig-Universität Giessen, Heinrich-Buff-Ring 16, D-35392 Giessen, Germany

In my talk I would like to discuss the mechanism of formation of the compound nucleus in the fusion of heavy ions leading to superheavy elements. The ideas are based on a quantum-statistical approach that makes use of (i) a master equation for the probability distribution of the nuclear shapes, and (ii) the two-center shell model to obtain the microscopic ingredients of the theory. Some examples of cold and hot fusion reactions will be presented and discussed.
