A. Ghiorso at the Lawrence Berkeley National Laboratory announced that, while they had been unable to confirm the Dubna group's results, they had identified at least two isotopes of element 104 different from the one identified by the Soviet scientists. They bombarded californium-249 atoms with carbon-12 and carbon-13 ions to creates isotopes with mass numbers 257 (half-life of 4.8 sec), 259 (half-life of 3 sec), and possibly 258 (half-life of 13 msec). Disputing the Soviet claim of discovery, the Americans suggested the name rutherfordium to honor the British physicist Lord Ernest Rutherford. An international committee set up to resolve such disputes decided in 1992 that the Berkeley and Dubna laboratories should share credit for the discovery. The syntheses of at least 10 isotopes of rutherfordium, with half-lives ranging from 0.5 msec (Rf-254) to 65 sec (Rf-261), have been confirmed.
Rutherfordium was first time obtained by Gheorghi Nikolaevici Flerov, Iuri Ţolakovici Ohanessian, Iuri V. Lobanov, V. I. Kuzneţov, V.A. Druin, V.P. Pereligin, K.A. Gavrilov, S.P. Tretiakova, V. M. Plotko in 1966 (Dubna, Russia), bombarding 242Pu with 22Ne.
A long controversy with an American team is mentioned, solved by IUPAC in 1997.
