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.

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.

BERKELEY, CA The team of Berkeley Lab scientists that announced two years ago the observation of what appeared to be Element 118 -- heaviest undiscovered transuranic element at the time -- has retracted its original paper after several confirmation experiments failed to reproduce the results.

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.
