    "abstract": "We study the isospin dynamics in fragment formation within the framework of\nan analytical model based on the spinodal decomposition scenario. We calculate\nthe probability to obtain fragments with given charge and neutron number,\nfocussing on the derivation of the width of the isotopic distributions. Within\nour approach this is determined by the dispersion of N/Z among the leading\nunstable modes, due to the competition between Coulomb and symmetry energy\neffects, and by isovector-like fluctuations present in the matter that\nundergoes the spinodal decomposition. Hence the widths exhibit a clear\ndependence on the properties of the Equation of State. By comparing two systems\nwith different values of the charge asymmetry we find that the isotopic\ndistributions reproduce an isoscaling relationship.",
