Do medium heavy fragments give evidence for a liquid gas phase transition?

An inclusive measurement of light and medium heavy fragments for eight projectile target combinations and incoming energies is presented. The energy spectra of all fragments are fitted consistently with a moving source parametrization. The results are compared to several model predictions. No evidence for the liquid gas phase transition of nuclear matter is found and considerable doubts in thermal interpretations arise. An alternative model of a cold shattering of the target nucleus is able to explain the energy spectra well but fails to reproduce the charge spectra.
