The Kohn variational method has recently been applied to the calculation of the addition to the Coulomb phase shift, in positron scattering, by the hydrogen molecular ion below the positronium-formation threshold at 9.45 eV. In this paper the wave function obtained for the lowest spheroidal partial wave of [Formula: see text] symmetry is used to calculate the contribution to Zeff from this symmetry. The results are significantly larger than those obtained using the Coulomb–Born approximation.

The dependence of the pp Coulomb phase shift on the form of the proton charge distribution function is studied and discussed. The uniform, exponential and Gaussian distributions are used. The dependence- on the form of the charge distribution for impact parameter values less than the radius of the proton is clear. The charge distribution effect leads to a decrease in the absolute value of the Coulomb phase shift.
