First results are reported from a recent experiments with neutron-rich uranium fragments at the FRS-ESR facilities. 670 MeV/u ²³⁸U projectiles with an intensity of 1-2*10⁹particles/spill were fragmented in 4 g/cm^{2 9}Be target placed in front of the fragment separator FRS. The FRS was used to separate the fragments in flight and to inject them into the storage-cooler ring ESR. Time resolved Schottky Mass Spectrometry was applied to measure the revolution frequencies of stored and electron-cooled ions. Preliminary results on masses and half-lives of neutron-rich nuclides in the lead area will be presented.
