2 AT ONE BLOW - THE NEW CHEMICAL-ELEMENTS 110 AND 111

Superheavy platinum and gold—the elements 110 and 111—were generated by nuclear fusion of nickel with lead or bismuth in November/December 1994 at the Darmstadt heavy‐ion accelerator and were unequivocally identified from their α‐decay into known atomic nuclei. The picture shows this explored end of the nuclide chart. Unexpectedly high production rates and sufficiently long half‐lives suggest that still heavier elements can be created and detected.
