ResumoThe mass yield and the charge dispersion of secondary fragments produced in high-energetic proton-xenon bombardment are analysed in the frame of our statistical multifragmentation model. The critical mass distribution as well as the charge dispersion, which have led to the discussion of a nuclear liquid-gas phase transition, are easily reproduced within our model. A clear signal of a “phase transition” at T=5 MeV is found and is analysed in terms of various multifragment correlations.
