Fragmentation of $Xe^{129}$ in the liquid-gas phase transition region

We analyzed the fragmentation of the $Xe^{129}$ nucleus to determine the effects of surface and symmetry energies ont he fragment distributionon the basis of the statistical multifragmentationm odel. Relative yields of fragments were classified with respect to the mass number of the fragments in the transition region. It was found that the symmetry energy of the hot fragments produced in the statistical freezeout is very important for isotope distributions. However, its influence on the mean fragment mass distributions is negligible. On the other hand, it was demonstrated that surface energy significantly influences the fragment distribution while the symmetry energy contribution remains negligible.
