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 Peace Medal institutions that have rendered ""outstanding services to peace and international understanding"". By tradition, the gold medal, together with a leather-bound diploma inlaid in gold, is presented in Berlin at a biennial ceremony on 17 December by the Governing Mayor of Berlin and the President of the DGVN. On 17 December 1938, in Berlin-Dahlem, Otto Hahn and his assistant Fritz Strassmann had discovered a new reaction in uranium (which exiled Lise Meitner and her nephew Otto Frisch two weeks later correctly interpreted as "nuclear fission") thus laying the scientific and technical foundations of nuclear energy. This 17 December 1938 therefore marks
