Abstract
A first application of the Kohn method is made to the calculation of s cattering parameters for positron collisions with the hydrogen molecul ar ion below the positronium formation threshold at 9.45 eV. Phase shi fts from the two-centre Coulomb value are obtained for the lowest sphe roidal partial wave of Sigma(g)(+) symmetry. For energies as low as 1. 2 eV, it is found that a very flexible trial function must be used if accurate results are to be obtained.
