Abstract

The production cross sections of neutron-rich fission residues in reactions induced by ${}^{238}U$ projectiles at $950 A$ MeV impinging on Pb and Be targets are investigated at the Fragment Separator at GSI. These two targets allow us to investigate fission processes induced by two reaction mechanisms, Coulomb and nuclear excitations, and to study the role of these mechanisms in the neutron excess of the final fragments.
