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 Hahn Centers" in Göttingen and Ottobrunn (near Munich), and planned in the near future also in Hahn's native city Frankfurt/Main, while in 2011 the city of Albstadt created an "Otto Hahn Memorial place" in her local IHK-Academy, focussed on Hahn's work in Tailfingen at the end of World War II. In early 2014, the University of Dortmund opened two new "Otto Hahn Libraries" in her General University Library, which are specialized in the natural sciences and technologies. At the end of 1999, the German news magazine "Focus" published an inquiry of 500 leading natural scientists, engineers, and physicians about the
