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 on a Be target. The preliminary analysis indicates the presence of previously unreported isomeric states in the N = 128 isotones 208Hg and 209Tl.
