摘要：

.The reactions Xe-136 + p and Xe-136 + C-12 have been studied in inverse kinematics at 1 A GeV with the SPALADiN setup at GSI. The detection in coincidence of the final-state charged particles (projectile residues, nuclei of charge Z2 and neutrons was performed with a big-aperture dipole magnet and large-acceptance detectors. This provided an extended coverage of the phase space of decay products of the prefragment formed at the end of the intranuclear cascade. This coincidence measurement, performed on an event-by-event basis permits both an estimate of the excitation energy of the prefragments and a determination of their deexcitation channels. The element production cross sections are compared with existing data and theoretical models. The evolution of observables such as the total multiplicity or the fragment production with the prefragment's excitation energy is studied for both reactions and compared with models.
