The process of complete fusion of nuclei within the framework of the dinuclear system concept

A non-traditional approach to the description of the process of complete fusion of nuclei - the dinuclear system concept (DNSC) is discussed. The DNSC reveals two important peculiarities of complete fusion of massive nuclei: the existence of a specific inner fusion barrier Bfus* and the competition between the complete fusion and quasi-fission channels in the dinuclear system, which is formed on the capture stage. The DNSC was applied in the analysis of reactions used for the synthesis of transfermium and superheavy elements, . (author)
