Darmstadtium was discovered by S. Hofmann (DE) et al. collaboration at the Heavy Ion Research Laboratory (Gesellschaft für Schwerionenforschung, GSI) in Darmstadt, Germany in November 1994. The title honours the Laboratory for Heavy Ion Research (called GSI) in Darmstadt, Germany, where the substance was first made. It is a synthetic radioactive metal. The fusion–evaporation reaction using a 62Ni beam on an isotopically enriched 208Pb target produced four chains of alpha-emitting nuclides following the presumed formation of 269110 + 1n.
