Spallation-reaction cross-sections relevant for accelerator-driven systems

Experiments of spallation in inverse kinematics were performed at GSI. The isotopic distribution cross-sections of the residual nuclides of spallation were measured for each element. The fragment separator (FRS) was used to s elect and identify the reaction products, and the full (Z, N) map was measu red. The velocity distributions of all products are determined with the hig h resolution of the spectrometer, which give further information on the rea ction mechanism. These data are relevant for the design of accelerator-driv en subcritical reactors. They are also of the highest importance to improve the understanding of the spallation mechanism.
