    "abstract": "A general model for the fragmentation of a two-component system (e.g. protons\nand neutrons) is proposed and solved exactly. The extension of this model to\nany number of components is also shown to be exactly solvable. A connection\nbetween this models and the permutation group is discussed. The notion of\nisotopic equivalence is defined in order to evaluate the equivalence of these\nmodels to earlier one-component models. All the one-component models considered\nin earlier papers are shown to be equivalent to a particular class of\ntwo-component models. A simplified model applicable to the case of nuclear\nfragmentation is introduced and analyzed. Modifications to this model to\ninclude effects such as pairing and Coulomb interactions are discussed.",
