摘要：

We have measured production cross-sections of the new neutron-rich isotopes 58Ti, 63Cr, 66Mn, 69Fe, 71Co and neighbouring isotopes that have been identified as projectile fragments from reactions between a 500 MeV/u Kr-83 beam and a beryllium target. The isotope identification was performed with thc zero-degree magnetic spectrometer FRS at GSI, using in addition time-of-flight and energy-loss measurements. The experimental production cross-sections for the new nuclides and neighbouring isotopes are compared with an empirical parametrization. The resulting prospects for reaching even more neutron-rich isotopes, such as the doubly-magic nuclide 78Ni, are discussed.
