    • Abstract


      A new, non-perturbative, coordinate space method is formulated to calculate the full and partial wave amplitudes for the potentialaeλr/r withλ=+0. The basic ingredients are a plausible use of the point Coulomb wave function up to moderate distances and a Wronskian identity to take care of the large distance behaviour of integrands.
