Modern approaches to the interaction of composite particles in nuclear and, partly, atomic physics are reviewed. The main attention is devoted to the effects of the Pauli principle in systems of two and three composite particles. Modified Faddeev equations are derived for a system of three composite particles, and the construction of variational bases for such systems is discussed in detail. The general concepts of ghost channels and ghost states, which are eigenstates of the total Hamiltonian with symmetry forbidden by the Pauli principle, are introduced. Some model examples are investigated for systems of three and four particles, in which a rigorous microscopic treatment is possible, and these examples are used to illustrate the meaning of the forbidden states and the optical potentials for scattering of composite particles. The structure of the carbon nucleus in the 3..cap alpha.. model is discussed as an example.
