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 In 1957, Hahn was elected an honorary citizen of the city of Magdeburg, DDR (German Democratic Republic) and, in 1958, an honorary member of the Academy of Sciences of the USSR (today Russian Academy of Sciences) in Moscow, but he declined both honors. In 1966, US President Lyndon B. Johnson and the United States Atomic Energy Commission (AEC) in Washington awarded Hahn (together with Lise Meitner and Fritz Strassmann) the Enrico Fermi Award (with a gold medal and citation). The diploma for Hahn bears the words: "For pioneering research in the naturally occurring radioactivities and extensive experimental studies culminating in
