Björn Jonson (physicist)
Björn Jonson (* 1941 ) is a Swedish nuclear physicist .
Jonson received his doctorate from TH Chalmers in 1972 (Beta-delayed proton emission from isotopes of mercury, cesium, xenon and krypton). From 1985 he was professor of physics (most recently for subatomic and plasma physics) at the TH Chalmers.
In 1987 he and P. Gregers Hansen interpreted phenomena in the core-core scattering at the LBNL as a halo core . He has been researching at CERN since 1970 , as a Staff Physicist from 1976 and as a Senior Staff Physicist from 1980 to 1984. His last research there was at the ISOLDE accelerator facility, the collaboration of which he headed from 1988 to 1991. In particular, he researches phenomena in exotic nuclei, with applications in nuclear astrophysics.
In 1997 he received a Humboldt Research Award . He is a Fellow of the Institute of Physics and a member of the Academia Europaea (2012). From 1991 to 1993 he was on the Scientific Policy Committee of CERN.
From 1997 he was a member of the Royal Swedish Academy of Sciences (and from 2002 to 2008 its council), in 1988 of the Royal Danish Academy of Sciences, in 1998 of the Academy in Gothenburg and from 2006 to 2013 member of the Nobel Committee for Physics (2012 as chairman). From 2001 to 2006 he was head of the Swedish Physical Society.
In 2017 he received the Lomonosov Gold Medal for work on core structure and core stability of the lightest exotic cores at the limits of stability.
