We derive a coordinate space approach to energy-dependent separable potentials and clearly demonstrate its calculational advantage. The results presented include expressions for (i) low-energy scattering parameters and (ii) off-energy-shellT andK matrices. We study energy dependence of the effective potential with particular emphasis on cross-channel suppression effects.
