Abstract

original image

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.
