N2 - The configuration interaction (CI) method is one of the most commonly used methods for the calculation of the electronic structure of atoms. The standard CI method based on a linear combination of orthonormal orbitals centered on the nucleus has been adapted to the calculation of the structure of exotic atoms containing one or two electrons and a positron. Results of calculations on a number of systems, including positronium hydride (PsH), e+Cu, e+Li, e+Be, e+Cd and CuPs show both the strengths and limitations of the CI approach for positron binding atoms.
