Discovery: 1984 Peter Armbruster, Gottfried Münzenber & GSI Darmstadt (DE)

Hassium was discovered by Peter Armbruster, Gottfried Münzenber (DE) and their co-workers at the Heavy Ion Research Laboratory (Gesellschaft für Schwerionenforschung, GSI) in Darmstadt, Germany in 1984. The origin of the name is the Latin word 'Hassias' meaning 'Hess', the German state. It is a synthetic radioactive metal. Hassium was produced by bombarding lead-208 with iron-58.
