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 highly significant for nuclear physics". Not until 1936 did Carl Friedrich von Weizsäcker provide a theoretical explanation of the phenomenon of nuclear isomerism. For this discovery, whose full significance was recognized by very few, Hahn was again proposed, from 1923 till 1929, for the Nobel Prize in Chemistry by Naunyn, Goldschmidt, and Max Planck. In the early 1920s, Otto Hahn created a new field of work. Using the "emanation method", which he had recently developed, and the "emanation ability", he founded what became known as "applied radiochemistry" for the researching of general chemical and physical-chemical questions. In 1936 Cornell University
