Abstract

Some highlight examples on the study of production and chemical properties of heaviest elements carried out mostly at GSI Darmstadt are presented. They focus on the production of some of the heaviest known elements (114Fl, 115Mc, and 117Mc), studies of non-fusion reactions, and on chemical studies of 114Fl. This is the heaviest element, for which chemical studies have been performed to date.


Dedicated to: The memory of Professor Günter Herrmann.


Acknowledgments

It is my pleasure to thank the members of my group at the Institute of Nuclear Chemistry at Johannes Gutenberg University Mainz and the Helmholtz Institute Mainz as well as at GSI Darmstadt, but also the many colleagues from institutes around the world who play an important role in our superheavy element research pursued at GSI and elsewhere. Without them, all of the work presented in this article – with much of it going back to groundbreaking work of Günter Herrmann – would not have been possible.
