    "abstract": "Within the statistical multifragmentation model we study modifications of the\nsurface and symmetry energy of primary fragments in the freeze-out volume. The\nALADIN experimental data on multifragmentation obtained in reactions induced by\nhigh-energy projectiles with different neutron richness are analyzed. We have\nextracted the isospin dependence of the surface energy coefficient at different\ndegrees of fragmentation. We conclude that the surface energy of hot fragments\nproduced in multifragmentation reactions differs from the values extracted for\nisolated nuclei at low excitation. At high fragment multiplicity, it becomes\nnearly independent of the neutron content of the fragments.",
