Recent experimental results with uranium fragments at the FRS.

New experimental results were obtained with relativistic exotic nuclei produced via uranium projectile fragmentation and projectile fission at the in-flight separator FRS. 60 neutron-rich isotopes have been discovered in the element range from Nd to Ac and their production cross sections have been measured. In other experimental campaigns the fragments were separated in flight and injected into the storage-cooler ring ESR for accurate mass- and lifetime measurements. New mass values have been measured for 33 nuclides in the element range from Pt to U circulating in the ESR. The systematic error has been reduced to about 10 keV which was possible by a new evaluation method. [ABSTRACT FROM AUTHOR]
