Fission fragments of 1A GeV238U nuclei interacting with a deuterium target have been investigated with the Fragment Separator (FRS) at Gesellschaft für Schwerionenforschung (GSI) by measuring their isotopic production cross sections and velocities. Results, along with those obtained recently for spallation-evaporation fragments, provide a comprehensive analysis of the spallation nuclear productions in this reaction. Details about the experimental performance, data reduction and results are presented.
