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 highly significant for nuclear physics". Not until 1936 did Carl Friedrich von Weizsäcker provide a theoretical explanation of the phenomenon of nuclear isomerism. For this discovery, whose full significance was recognized by very few, Hahn was again proposed, from 1923 till 1929, for the Nobel Prize in Chemistry by Naunyn, Goldschmidt, and Max Planck. In the early 1920s, Otto Hahn created a new field of work. Using the "emanation method", which he had recently developed, and the "emanation ability", he founded what became known as "applied radiochemistry" for the researching of general chemical and physical-chemical questions.
