Isotopic production cross sections and momentum distributions of more than 1400 residual nuclei produced in the collision of 238U(1 AGeV)+2H have been measured. The experiment was performed at GSI where we could take profit of the inverse kinematics technique and the high-resolution magnetic spectrometer FRS to identify in atomic and mass numbers all the produced nuclei. The identification technique challenges for the case of 238U are reviewed. Some features of 238U residues are discussed, including the access to information of fission dynamics.
