The element 112, Ununbium (symbol Uub), also known as eka-mercury was synthesized on 9th February 1996 at 22:37 at SHIP, Gesellschaft fur Schwerionenforschung in Darmstadt, Germany. The name Ununbium is a systematic IUPAC name for this element, which should be changed sooner or latter. In the first experiment only two nuclei of Ununbium-277 were synthesized by bombarding of the lead target by accelerated in a heavy ion accelerator zinc ions.
Subsequntly, Ununbium was synthesized in Joint Institute for Nuclear Research, Dubna, Russia. In 2006, in Dubna, another isotope Ununbium-282 was synthesized via series of α-decays. |
