SHE Research with Rare-Isotope Beams, Challenges and Perspectives, and the New Generation of SHE Factories

SHE research at GSI is strongly inspired by the ideas of Walter Greiner. He developed the theoretical concept of cold heavy-ion fusion, the use of magic nuclei for SHE production which was successful to create super heavy elements at GSI. Later the concept of magic nuclei for SHE production has been applied to hot fusion at JINR Dubna. A large region of super heavy elements extending even beyond element 114 has been discovered. The discovery of the spherical SHE is still waiting. New ideas to surpass the present limit at Z = 118 and to access the region of spherical SHE are needed. In this paper the perspectives for SHE production with rare-isotope beams will be discussed in the light of the new generation of SHE factories with intense beams. New experimental developments such as a setup for spectroscopic studies at the GSI SuperFRS and a next-generation in-flight separator with direct isotope identification will be addressed.
