For the investigation of few-body binding energy correlations, Lippmann-Schwinger-type equations with a simple structure of kernels have been used. This note presents N-body integral equations with simple kernel structures for the scattering of two composite particles in the incoming channel. Only the bound-state part of the subsystem Green's functions are used. This approach leads to coupled equations with kernels consisting of two-body interactions, the free Green's function, the bound-state wave function of the N-1, N-2, ..., two-body subsystem and the corresponding poles. Thus, in order to calculate an N-body t-amplitude, one must first calculate only the N-1, N-2, ..., two-body bound states and binding energies. In the low-energy region there is another advantage. If the scattering energy lies below some cluster breakup threshold, one can omit the pole corresponding to this cluster. (RWR)
