Progress is reported on the data analysis of a recent experiment at the FRS-ESR facilities. 670 MeV/u ²³⁸U primary beam was fragmented in 4 g/cm^{2 9}Be target placed in front of the fragment separator FRS. The FRS separated neutron-rich fragments in flight, which were then injected into the storage-cooler ring ESR. Time resolved Schottky Mass Spectrometry was applied to measure the revolution frequencies of stored and electron-cooled ions. The results on masses and/or new isomeric states of neutron-rich nuclei in the lead area will be presented.
