          Abstract

          The RSE Born Approximation is a new scattering formula in Physics, it allows the calculation of strong scattering at all frequencies via the Fourier transform of the scattering potential and Resonant-states. In this paper I apply the RSE Born Approximation to Schrodinger's equation. The resonant-states of the system can be calculated using the recently discovered RSE perturbation theory and correctly normalised to appear in spectral Green's functions via the flux-volume normalisation. In the limit of an infinite number of resonant states being used in the RSE Born Approximation basis the approximation converges to the exact solution. In the case of effectively 1-dimensional systems I find an RSE Born Approximation alternative to the scattering matrix method.
