| Inclusive multi-neutron and multi-proton removal cross sections from 112Sn and 104Sn at relativistic energies have been measured. The data show two distinct regimes of the reaction process depending on the nucleon evaporation cost of the final nucleus. This behaviour is universal regarding the mass or asymmetry of the initial system or target composition. A state-of-the-art cascade and de-excitation model reproduces the observed trend but systematically fails in reproducing cross sections for the removal of the more bound nucleon species. |
