Darmstadtium team proposed the name "becquerelium" after Henri Becquerel. The American team in 1997 proposed the name "hahnium" after Otto Hahn (previously this name had been used for element 105). The name "darmstadtium" (Ds) was suggested by the GSI team in honor of the city of Darmstadt, where the element was discovered. The GSI team originally also considered naming the element "wixhausium", after the suburb of Darmstadt known as Wixhausen where the element was discovered, but eventually decided on "darmstadtium". The new name was officially recommended by IUPAC on August 16, 2003. Darmstadtium has no stable or naturally occurring isotopes. Several
Otto Hahn (ship) She had covered 250,000 nautical miles (463,000 km) on 22 kilograms of uranium. In 1979 "Otto Hahn" was deactivated. Her nuclear reactor and propulsion plant were removed and replaced by a conventional Diesel engine room. In nine years, she had travelled 650,000 nautical miles (1,200,000 km) on nuclear power, visiting 33 ports in 22 countries. The containment vessel of the nuclear reactor is stored at the Helmholtz-Zentrum Geesthacht – Zentrum für Material- und Küstenforschung GmbH and the nuclear fuel in the United States. In 1983, "Otto Hahn" was recommissioned as the container ship "Trophy" and leased into commercial service. On
