摘要：

Using techniques related to factorizability and supersymmetry we construct solvable coupled channel problems. Their physical interpretation is clarified by expressing the scattering solution of the coupled problem as superposition of scattering states of a decoupled problem. A discussion is given about orthogonality of solutions corresponding to different energies and about the unitarity of the S matrix.
