Abstract The Orthogonalising Pseudo-Potential (OPP) introduced by Kukulin and Krasnopolsky is applied to scattering problems. Two simple models admitting analytic solution were used to illustrate the behaviour of the scattering states as a function of the OPP strength parameter. These were a system with a zero-range potential having one bound state, and free particle scattering subject to an orthogonality constraint. Application of the OPP to electron scattering from helium in a modified static exchange model, and Ps scattering from He in an s-wave model, were used to demonstrate that the results derived from the model-potential analysis are also valid in a numerical calculations.
