The systematics of the production rates of stable and unstable nuclei from the nuclear collision are studied so as to unify different methods of analyses under a simple basic physical treatment. It is found that the isotope production rates are well expressed by the binding energy and the mass excess of the produced nucleus under two different thermalization processes: Fast high energy and so-called evaporation processes.
