Roentgenium Element 111 was officially discovered by Peter Armbruster, Gottfried Münzenber, and their team working at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany on December 8, 1994.[2] Only three atoms of it were observed (all 272Rg), by the cold fusion between 64Ni ions and a 209Bi target in a linear accelerator: 20983Bi + 6428Ni → 272111Rg + 10n In 2001, the IUPAC/IUPAP Joint Working Party (JWP) from concluded that there was insufficient evidence for the discovery at that moment in time.[3] The GSI team repeated their experiment in 2000 and detected a further 3 atoms.[4][5] In their 2003 report, the JWP decided that the GSI team should be acknowledged as the discoverers.
