Convincing Evidence Seen for Isotopes of Element 110

On 9 November a group of researchers led by Peter Annbruster and Sigurd Hofmann at the Gesell‐schaft für Schwerionenforschung (GSI) in Darmstadt, Germany, observed a sequence of four alpha particles emitted from selected reaction products of a thin piece $Pb208$ under bombardment from a beam of 311‐MeV $Ni62$ ions. The alphas clearly represented a decay chain, being essentially coincident in position and following one another at intervals ranging from a few hundred microseconds to a few hundred milliseconds. Indeed, the last three alphas had energies and delay times that clearly matched the decay chain
