 Later calculations suggest that the cross section of the 3n reaction (which would result in 299Uue and three neutrons as products) would actually be six hundred thousand times lower than this upper bound, at 0.5 pb.As ununennium is the lightest undiscovered element, it has been the target of synthesis experiments by both German and Russian teams in recent years.The Russian experiments were conducted in 2011, and no results were released, strongly implying that no ununennium atoms were identified.
