Dubnium not have enough experimental data to back their claim. After collecting more data, JINR proposed the name "nielsbohrium" (Ns) in honor of the Danish nuclear physicist Niels Bohr, a founder of the theories of atomic structure and quantum theory. When LBL first announced their synthesis of element 105, they proposed that the new element be named "hahnium" (Ha) after the German chemist Otto Hahn, the "father of nuclear chemistry", thus creating an element naming controversy. In the early 1970s, both teams reported synthesis of the next element, element 106, but did not suggest names. JINR suggested establishing an international committee
Otto Hahn as the name for one of Hahn's newly discovered elements - meaning "parallel to radium" - Hahn rejected the suggestion on the grounds that the name was too reminiscent of military activity and goose-stepping. In 1914, for the discovery of mesothorium I (radium-228), Otto Hahn was first nominated for the Nobel Prize in Chemistry by Adolf von Baeyer and, in June 1907, by means of the traditional "habilitation" thesis, Hahn qualified to teach at the University of Berlin. On 28 September 1907 he made the acquaintance of the Austrian physicist Lise Meitner who was almost the same age, who had
