    Abstract

    The Harris-Nesbet algebraic close-coupling method is used to calculate the S-wave phase shift and positronium-formation cross section for various types of close-coupling expansions of the total wave function. The positronium channels are included explicitly, and polarization effects, in both the hydrogen and positronium atoms, are incorporated by pseudostates that give the correct static polarizabilities.
