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 Peace Medal institutions that have rendered ""outstanding services to peace and international understanding"". By tradition, the gold medal, together with a leather-bound diploma inlaid in gold, is presented in Berlin at a biennial ceremony on 17 December by the Governing Mayor of Berlin and the President of the DGVN. On 17 December 1938, in Berlin-Dahlem, Otto Hahn and his assistant Fritz Strassmann had discovered a new reaction in uranium (which exiled Lise Meitner and her nephew Otto Frisch two weeks later correctly interpreted as "nuclear fission") thus laying the scientific and technical foundations of nuclear energy. This 17 December 1938 therefore marks
