Helmholtz International Fellow Award for discoverer of halos



Professor Björn Jonson, member of the Nobel Committee in physics and professor at the Chalmers University of Technology (Sweden), received the Helmholtz International Fellow Award. The award is endowed with 20.000 Euro and enables the awardees to stay at a Helmholtz Centre for research purposes.

Jonson is famous for discovering the halo nucleus in 1987. From experiment data gathered at BEVALAC (USA) he and his colleague Hansen suggested the existence of these nuclei with nucleons far away from the centre. Jonson is closely connected to the GSI Helmholtzzentrum für Schwerionenforschung where he will spend his research period. He took part in building the GSI synchrotron SIS18 and the fragment separator. He also plays a leading role within the NuSTAR collaboration (Nuclear Structure Astrophyics and Reactions) of FAIR. He was awarded for these achievements. Moreover the research period at GSI will allow Jonson to further heavy ion research.
