N2 - Seven previously unobserved neutron-rich isotopes (209Hg, 210Hg, 211Tl, 212Tl, 218Bi, 219Po and 220Po) have been identified among the fragmentation products of a 1000 MeV/nucleon 238U beam incident on a beryllium target. The γ-ray decays of 9 known and 4 new μs-isomers in nuclei around 208Pb were also observed. Production cross sections and probabilities for populating isomeric states in the fragmentation reaction were determined and compared with a simple model based on the statistical abrasion-ablation approach.
