In October 2006, researchers announced that three atoms of [[oganesson]] (element 118) had been identified at [[Joint Institute for Nuclear Research]] in [[Dubna]], [[Russia]], from bombarding {{sup|249}}Cf with [[calcium-48]], making it the heaviest element ever made. The target contained about 10&nbsp;mg of {{sup|249}}Cf deposited on a titanium foil of 32&nbsp;cm{{sup|2}} area.<ref>{{cite journal |title = Synthesis of the isotopes of elements 118 and 116 in the californium-249 and <sup>245</sup>Cm+<sup>48</sup>Ca fusion reactions |journal = Physical Review C |date = 2006 |volume = 74 |issue =4 |pages = 044602–044611 |doi = 10.1103/PhysRevC.74.044602 |bibcode=2006PhRvC..74d4602O |last1=Oganessian |first1=Yu.
