Synthetic Paths to the Heaviest Elements

Walter Loveland, Oregon State University
6008 Conference Room

The heaviest elements provide a laboratory for studying nuclear structure and dynamics under the influence of large Coulomb forces. They offer opportunities for studying some of the most fundamental aspects of chemistry and physics. I review some of the recent developments in the chemistry of these elements. New results on the confirmation of the synthesis of element 110 (Ds) are reported along with new systematic studies of the synthesis of element 112 using hot fusion reactions. The story of the element 118 fiasco is told from an insider's perspective. New results on the survival probabilities of the heaviest elements (Z>=102) from neutron counting and evaporation residue detection are discussed. The role of radioactive nuclear beams in future studies of the heaviest elements is discussed.
