Numerical solutions of scattering integral equations — •Ivo Häring — Am Buntengraben 4, 79576 Weil-Haltingen

When examining analytical properties of quantum mechanical scattering various integral equations are elegant and effective tools (e.g. PRL 91 070403). However, actual computations of scattering quantities often resort to single or two point boundary value problems equivalent to the integral formulations. We numerically investigate direct solutions of the integral equations. For generic radial potentials and selected methods achievable accuracies and needed computational resources in terms of time and memory are discussed.
