Isomeric states in neutron-deficient nuclei around A approximate to 190 have been identified following the projectile fragmentation of a relativistic energy U-238 beam. The deduced isomeric ratios are compared with a model based on the abrasion-ablation description. The experimental isomeric ratios are lower by a factor of approximate to2 than the calculated ones assuming the 'sharp cutoff' approximation. The observation of the previously reported isomeric I-pi=43/2(-) state in Ra-215 represents the current record for the highest discrete spin state observed following a projectile fragmentation reaction.
