Description

The production of heavy neutron-rich nuclei has been investigated using cold-fragmentation reactions of 238U projectiles at relativistic energies. The experiment performed at the high-resolving-power magnetic spectrometer Fragment Separator at GSI made it possible to identify 40 new heavy neutron-rich nuclei: 205Pt, 207-210Au, 211-216Hg, 214-217Tl, 215-220Pb, 219-224Bi, 223-227Po, 225-229At, 230,231Rn, and 233Fr. The production cross sections of these nuclei were also determined and used to benchmark reaction codes that predict the production of nuclei far from stability.
