     The IUPAC/IUPAP JWP performed a critical review of the various claims to discovery of the trans-copernicium elements Z = 113, 114, 115, 116, and 118. Evidence in the cases of elements Z = 113, 115, and 118 have not met the criteria for discovery.

     The α–α correlation technique will fail here for element identification as already became clear with the new trans-copernicium elements.
