Page "Nobelium" Paragraph 10

In 1992, the IUPAC-IUPAP Transfermium Working Group ( TWG ) assessed the claims of discovery and concluded that only the Dubna work from 1966 correctly detected and assigned decays to Z = 102 nuclei at the time.

The Dubna team are therefore officially recognised as the discoverers of nobelium although it is possible that it was detected at Berkeley in 1959.
