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 free scientific enquiry, as well as in his efforts to persuade scientists to recognize their responsibility for shaping the contemporary world and the future, we found something which we could identify. And when in the fifties he came out so strongly and impressively against the misuse of nuclear science for aggressive purposes, we looked upon him as an example to us all. Another reason for the admiration we felt for Otto Hahn was that he never ceased to remind us of our duty to think not only of ourselves, and not only of the developed world, but of the world
