The element does not have a name yet, therefore the systematic IUPAC name is used (system explained at Ununoctium).

The second atom of 116 has been synthesized

These May holidays have been marked by new and important event in the Flerov Laboratory of Nuclear Reactions of JINR. These days the experiments on synthesis of superheavy element with atomic number 116 in the fusion reaction of ⁴⁸Ca cyclotron U-400 accelerated ions and ²⁴⁸Cm target nuclei are in progress here.

These experiments have started with Gas Filled Separator in June 2000. That time on the 35th day of irradiation the first atom of element 116 with neutron number 176 has been synthesized. Daughter nuclei properties of elements 114, 112 and 110 - element 116 alpha-decay products - were in full consent with the properties of isotopes got in the earlier experiment on synthesis of element 114 in the reaction with lighter target of ²⁴⁴Pu. To confirm their own results the scientists repeated these experiments at the turn of 2000 and in January 2001. But those experiments have failed to synthesize new atom.

The forth round of the experiments have started in late April. Now on May 2 after the full number of ⁴⁸Ca ions passed through the target during the time of the experiment has reached 2x1019 the work of the scientists has been crowned with new success. One more atom of element 116 has been synthesized and this entirely confirmed the former results. This second atom of element 116 gives full assurance that the new elements with atomic numbers 114 and 116 have been synthesized in the Laboratory. Their properties confirm the hypothesis on the existence of the new domain of enhanced stability of superheavy elements.
