In 1999, the team at Lawrence Berkley Labs published a paper in the journal Physical Review Papers proclaiming their discovery of element 118. The scientific community exploded, hoping that the decay time of 118 (eka-radon) would longer than that of 114. Element 116 was also synthesized during this reaction,

Within less than a millisecond after its creation, the nucleus of element 118 radioactively decays by emitting an alpha particle, leaving behind an isotope of element 116.

In experiments conducted at the JINR U400 cyclotron between February and June 2005, the researchers observed atomic decay patterns, or chains, that establish the existence of element 118. In these decay chains, previously observed element 116 is produced via the alpha decay of element 118.

After claims of its discovery were retracted in 2002, a new team of researchers says it has produced a few scant atoms of the heaviest element yet, called simply element 118 after the number of protons in its nucleus. ... Element 118 would then decay into element 116 and lighter elements by emitting a series of alpha particles,

By convention, the substance remains the Baby Doe of elements until its existence is confirmed at other laboratories. For now, the new substance will be principally known as element 118 for the number of protons in its nucleus, more than in any other element occurring naturally or produced in the laboratory.

Element 118 and its immediate decay product, element 116, were discovered at Berkeley Lab's 88-Inch Cyclotron by bombarding targets of lead with an intense beam of high-energy krypton ions. ... The isotope of element 118 with mass number 293 identified at Berkeley Lab contains 118 protons and 175 neutrons in its nucleus.
