Abstract
The INDRA multidetector has been used to study multifragmentation proc esses in central collisions for the Xe + Sn reaction at 50 A MeV. A si ngle isotropic source formed at an excitation energy of 12 A MeV exhau sting most of the emitted charged products has been isolated in such c ollisions. The fragment kinetic energy spectra indicate a fast disinte gration of the system with a radial collective motion of about 2 A MeV . The light charged particle characteristics within this scenario are also discussed.
