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. The IUPAC/IUPAP Joint Working Party (JWP) recognised the GSI team as discoverers in their 2001 report, giving them the right to suggest a name for the element. Using Mendeleev's nomenclature for
Otto Hahn their discovery Hahn and Meitner were repeatedly nominated for the Nobel Prize in Chemistry in the 1920s by a number of scientists, among them Max Bergmann, Viktor Moritz Goldschmidt, and even Fajans himself. In 1949, the International Union of Pure and Applied Chemistry (IUPAC) named the new element definitely protactinium, and confirmed Hahn and Meitner as discoverers. In February 1921, Otto Hahn published the first report on his discovery of uranium Z (later known as Pa ), the first example of nuclear isomerism. Gerlach remarked that this was "a discovery that was not understood at the time but later became
