In 1999, our group reported [1] the synthesis of element 118 in the Pb( Kr,n) reaction. Prompted by the
2
absence of similar decay chains in subsequent experiments [2–5] the original data files from our experiments [1]have
2
been re-analyzed. The reported chains are not in the original data files.

Therefore, the previously reported results [1] on the production and decay of element 118 are not valid.
