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 pupil and assistant Fritz Strassmann (1902–1980), Otto Hahn furthered the research begun by Enrico Fermi and his team in 1934 when they bombarded uranium with neutrons. Until 1938, it was believed that the elements with atomic numbers greater than 92 (known as transuranium elements) arose when uranium atoms were bombarded with neutrons. The German chemist Ida Noddack proposed an exception. She anticipated the paradigm shift of 1938/39 in her article published in the journal "Angewandte Chemie", Nr. 47, 1934, in which she speculated: It is conceivable that when heavy nuclei are bombarded with neutrons these nuclei could break down into
