Pauli-correct separable potentials for composite particle interactions

A method is presented which allows to derive separable two-cluster interaction potentials from wave functions of the fish bone optical model, or from resonating group wave functions. The two-cluster Pauli effect, as much as it is contained in the off-shell behaviour of the wave functions, is reproduced by the separable interaction. The potentials are real, symmetric and energy-independent. The α-α potential is given as an example. (orig.)
