Superheavy Elements at GSI and in Mainz on the way to FAIR
Prof. Dr. Christoph E. Düllmann (Institut für Kernchemie & PRISMA Exzellenzcluster, JGU; GSI, Darmstadt; Helmholtz-Institut Mainz)


Current superheavy element research activities at GSI and in Mainz encompass a variety of aspects of these elements; most pronouncedly their synthesis and decay properties, nuclear structure, atomic mass, and their chemical properties. I will give an overview of the status of the field and the rich program centered at Mainz and Darmstadt. Examples of recent highlights include search experiments for new elements with Z>118, studies of the (not yet officially acknowledged) elements with Z=113/115/117, high precision atomic mass measurements, the determination of the first ionization potential of lawrencium (element 103), which leads IUPAC to discuss the structure of the "official" periodic table of the elements, or the synthesis of new chemical compounds of superheavy elements like the seaborgium hexacarbonyl - Sg(CO)6 - molecule. I will close with discussing the perspectives of SHE research at the GSI/FAIR facility, highlighting the research possibilities arising from the development of a compact superconducting continuous wave linac, largely driven by scientists from HIM, GSI, and Frankfurt University.
