Abstract
Relative angle correlation functions for mid-rapidity protons built up from 50 MeV/u Xe+Sn data recorded by the INDRA multidetector exhibit the characteristics of a non-equilibrated emission: they show an energy dependent anisotropy which cannot be accounted for by standard evaporation processes; a possible explanation lies in the dynamical origin of these protons as suggested by a Landau-Vlasov simulation.
