5D model accurately predicts nuclear fission in elements beyond uranium and plutonium
A five-dimensional (5D) Langevin approach developed by an international team of researchers, including members from Science Tokyo, accurately reproduces complex fission fragment distributions and kinetic energies in medium-mass mercury isotopes (180Hg and 190Hg). The model successfully captures the unusual "double-humped" fragment mass distribution observed in mercury-180 and offers new insights into how nuclear shell effects influence fission dynamics—even at higher excitation energies than previously thought—advancing our understanding of fission in the sub-lead region.
