Description
Neutron-rich nuclides produced in fragmentation of 197Au projectiles were studied in the storage ring ESR. The nuclides were separated in flight with the fragment separator FRS and injected at relativistic energies of 400 MeV/u into the ESR. In the ESR the velocity spread of the ions was reduced by the stochastic and then electron cooling. The properties of cooled ions were investigated with time-resolved Schottky spectrometry, which allowed simultaneous measurement of their masses and lifetimes. In total 54 neutron-rich nuclides (69≤Z ≤79) have been identified. Five long-lived isomeric states were discovered in 183,184,186Hf and 186,187Ta. Masses for five nuclides and half-lives for three nuclides were determined for the first time. The experiment, the data analysis and the obtained results are presented.
