abstract:
The nuclear structure of neutron-rich N>126 nuclei has been investigated following their production via relativistic projectile fragmentation of a E/A=1 GeV 238U beam. Metastable states in the N=128 isotones 208Hg and 209Tl have been identified. Delayed γ-ray transitions are interpreted as arising from the decay of Iπ=(8+) and (17/2+) isomers, respectively. The data allow for the so far most comprehensive verification of the shell-model approach in the region determined by magic numbers Z<82 and N>126.
