In this study, target fragment recoil properties were measured using the thick-target—thick-catcher technique for the interaction of 4.8 GeV ¹²C and 5.0 GeV ²⁰Ne with ²³⁸U. The target fragment energies and momenta are very similar for the reaction of 4.8 GeV (400 MeV/nucleon) ¹²C and 5.0 GeV (250 MeV/nucleon) ²⁰Ne with ²³⁸U. In the complex variation of fragment momenta with their NZ ratio, one finds evidence suggesting the existence of several mechanisms leading to the formation of the target fragments. In conclusion, comparison of these results with the predictions of the intranuclear cascade model of Yariv and Fraenkel and the firestreak model shows that both model predictions grossly overestimate the target fragment momenta.
