The fragmentation of neutron-rich Sn isotopes obtained from the fission of U-238 projectiles at 950 MeV/u has been investigated at the FRagment Separator (FRS) at GSI. In order to study the feasibility of a two-step reaction scheme for the production of medium-mass neutron-rich nuclei, fragments with masses A approximate to 130 have been isotopically resolved in the first part of FRS and their fragmentation residues identified in the second part.
