Description
At GSI Darmstadt we perform experiments on fusion and transfer reactions in very heavy collision systems like e.g. Ca+Pb up to U+U at beam energies below and around the Coulomb barrier (≈ 4 to 6 MeV/u). A main goal is the synthesis and investigation of heavy and superheavy nuclei which are produced in fusion reactions at the velocity filter SHIP. Additionally, we perform studies of the fusion process in very heavy systems what is still a hardly understood process from experimental as well as theoretical point of view. According to some theoretical models, fusion and nucleon transfer are regarded as closely related processes in the sense that transfer is assumed as first step to fusion of heavy systems. In this context we study transfer reactions in the heaviest systems at SHIP and other setups. On the other hand, we investigate transfer reactions also as a means to synthesize new exotic heavy isotopes which are not reachable in other reactions.
For the future, when appropriate facilities become available, we plan to extend our experiments to reactions with radioactive beams which promise for certain reactions many orders of magnitude larger cross-sections and accessibility to isotopes which cannot be reached with stable beams. This presentation will give an overview on our present activities, possible future experiments with radioactive beams and appropriate experimental setups.
