Newly Detected Seaborgium-257 Offers Critical Data on Fission and Quantum Shell Effects
German Scientists at GSI Helmholtzzentrum für Schwerionenforschung found a new superheavy isotope, 257Sg, named Seaborgium, which reveals unexpected details about the stability and nuclear fission. This study was published in Physical Review Letters and describes how this isotope, made by fusing chromium-52 with lead-206, survived for 12.6 milliseconds, longer than usual. The rare longevity and […]
