Heavy neutron-rich nuclei close to the neutron closed shell N = 126 were produced by fragmentation of a 1 A GeV 208Pb beam in a beryllium target at the Fragment Separator at GSI. Around 30 heavy neutron-rich isotopes have been synthesized for the first time and the half-lives of some of them have been determined.
