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 that formation of light elements was occurring in his setup that he published a new revision of the article, essentially retracting former claims of observing transuranic elements and neighbors of uranium, and concluding instead that he was seeing light platinoids, barium, lanthanum, and cerium. Fritz Strassmann recollects: As a chemist, Hahn was reluctant to propose a revolutionary discovery in physics. However, Meitner and her nephew, the young physicist Otto Robert Frisch, in Sweden, came to the same conclusion (a "bursting") as Hahn and were able, because they had a lead of time, to work out the first theoretical interpretation of
