Announcement of the discovery of element 111 was made in the popular press in January of 1995. Reports from the GSI labs in Germany indicate that nickel ions were used to bombard a bismuth target. The IUPAC in 2004 confirmed the discovery by S. Hoffmann and his coworkers in Darmstadt, Germany. The researchers proposed the name Roentgenium, with symbol Rg. Final approval was given in November 2004.
