We investigate the importance of various multiple-scattering corrections to electron propagation in near-edge X-ray absorption spectra using the 0/Ni(100) system as an example. We find that within approximately 10 of the absorption edge multiple scattering contributions cannot be neglected, though for greater energies the convergence of all perturbation schemes is quite rapid. We also outline our recently developed geometric series representation of renormalized forward scattering perturbation theory.
