 Production and $\beta$-Decay Half-Lives of Very N-rich Nuclei

 (2000)
 Investigations of extremely neutron-rich nuclei are bringing signifiant information; neutron halos, neutron skin and other surprises already appear on the frontier of the nuclear binding. We have initiated the experimental study of fission of U-projectiles at relativistic energies withe the FRS (GSI) in which 117 new n-rich isotopes have been separated and unambiguously identified. They will be further investigated starting with half-life (t$_1/2$) and the mass-excess (m.e.) measurements. The first or the second of these quantities has already been measured for 42 new n-rich isotopes of elements between Cu and Ti using different production techniques at the MP- tandem (IPN Orsay) , the on-line mass-separator (GSI-Darmstad), the nuclear reactor (ILL-Grenoble), and the FRS (GSI).
