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

On 4 December, Hahn was persuaded by two of his captors to write a letter to the Nobel committee accepting the prize but also stating that he would not be able to attend the award ceremony.

Broomé-Aminoff on November 20, 1945:Surely Hahn fully deserved the Nobel Prize in chemistry. There is really no doubt about it. But I believe that Otto Robert Frisch and
