Award of the Foundation for Polish Science for Prof. Hans Geissel


For his outstanding scientific achievements in the field of exotic nuclei the physicist Prof. Dr. Dr. h.c. Hans Geissel receives the Polish Alexander von Humboldt Award in Physics. Prof. Geissel is senior scientist in the FRS/Super-FRS research department at GSI Helmholtzzentrum für Schwerionenforschung and the Facility for Antiproton an Ion Research (FAIR GmbH) in Darmstadt as well as Professor at Justus-Liebig-Universität Gießen (JLU). The award, which involves the financing of a research stay, is granted by the Foundation for Polish Science (Fundacja na rzecz Nauki Polskiej, FNP), a partner organization of the German Alexander von Humboldt Foundation. The award is given to excellent active German scientists to honor their work and to enable them to carry out scientific research at a selected institution in Poland.

Prof. Geissel receives the award for his many years of successful studies with short-lived nuclei and the investigation of their properties. Together with the Polish scientists Prof. Dr. Zygmunt Patyk (National Center for Nuclear Research, Świerk-Warsaw) and Prof. Dr. Marek Pfützner (University of Warsaw) he realized pioneering experiments with the GSI fragment separator FRS. Together with Prof. Patyk and his research group, he was able for the first time to perform highly accurate mass measurements of exotic nuclei that were produced, separated at FRS and cooled in the storage ring ESR. The collaboration with Prof. Pfützner and his research group also resulted in many publications of worldwide acclaim, of which the discovery of numerous new isotopes and two-proton radioactivity are particularly outstanding. With a total of 276 isotopes discovered, Prof. Geissel has held the world record since 2012.

"This award naturally also represents an international recognition of the scientific work of the entire research group at the FRS and FRS-ESR", said Prof. Geissel. "I would also like to take this opportunity to thank my former teachers, Professors Heinz Ewald, Ulrich Mosel, Gottfried Münzenberg, Werner Scheid and Herrmann Wollnik, who showed me the way to ion research". In connection with the award, further research work of the international German-Polish collaboration is planned to be carried out until 2023. Japanese scientists are also involved in this. The first experiments were already successfully carried out at the FRS in spring of this year. Further research work at the accelerator facility FAIR in Darmstadt and at the Japanese research center RIKEN should form the basis for further scientific successes in the near future.

The two Polish institutions involved - the National Center for Nuclear Research and the University of Warsaw - are members of the Super-FRS Experiment Collaboration and thus belong to the NUSTAR (NUclear STructure Astro-physics and Reactions) activity at FAIR. Stays of Prof. Geissel with lectures are also planned at the University of Warsaw and the National Center for Nuclear Research in Warsaw, since the education and motivation of young physics students is a major concern of all participating institutions.

The Foundation for Polish Science annually awards prizes for works in various scientific disciplines. This year, in addition to Prof. Geissel, a scientist from the field of biomineralogy and a scientist from the field of history are honored. (JL)
