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) its primary purpose. It contained cabins for the group of about 36 scientists. It also contained a conference room, a meeting room and two laboratories. Its main purpose was to gain experience of future nuclear ships which could be used for transport. As the "Otto Hahn" did not receive enough permissions from harbours, the experiments ended in 1979, ten years after commissioning. Until its decommissioning, the Otto Hahn visited 33 ports in 22 countries, most of them in South America and Africa. It did not receive permission to pass through the Suez Canal and its last journey was to Durban.
