The most central collisions were selected by means of a multidimensional analysis. The characteristics of the source formed in the central collisions, as size, temperature and volume, were inspected. The measured isotopes of light fragments (3 <= Z <=8) were used to examine isotope yield ratios that provide information on the free neutron to proton densities.4 pages, Contribution to 8th International Conference on Nucleus-Nucleus Collisions, Moscow 2003Nuclear Experimenttext
