    "abstract": "The positron-hydrogen atom scattering system is considered within the S-wave\nmodel. Convergence in the elastic scattering, excitation, ionization, and\npositronium formation channels is studied as a function of the number and type\nof states used to expand the total wave function. It is found that all\nunphysical resonances disappear only if near-complete pseudostate expansions\nare applied to both the atomic and positronium centers.",
