Isotopic production cross sections of fission residues in 197Au-on-proton collisions at 800 AMeV

Interactions of 197Au projectiles at 800 AMeV with protons leading to fission are investigated. We measured the production cross sections and velocities of all fission residues which are fully identified in atomic and mass number by using the in-flight separator FRS at GSI. The new data are compared with earlier measurements of the characteristics of fission in similar reactions. Both the production cross sections and the recoil energies are relevant for a better understanding of spallation reactions.
