%X In the last decade the role and nature of pseudo states applied to scattering problems has become better understood. The J-matrix technique has provided a direct physical interpretation for the pseudo states. Recent work in constructing and applying pseudo-state expansions based on analytic techniques is reviewed and convergence questions relating to the use of such expansions in the close-coupling equations are addressed.
