Darmstadtium the JINR showed signs of Ds being produced from Pu and S. Each team proposed its own name for element 110: the American team proposed "hahnium" after Otto Hahn in an attempt to resolve the situation on element 105 (which they had long been suggesting this name for), the Russian team proposed "becquerelium" after Henri Becquerel, and the German team proposed "darmstadtium" after Darmstadt, the location of their institute.
