Abstract: The problem of recovering the asymptotics of a short range perturbation of the Euclidean Laplacian on \mathbb{R}^n from fixed energy scattering data is studied. It is shown that for n \geq 3 the asymptotics of a magnetic potential are determined, modulo Gauge invariance, by its scattering matrix at a fixed non‐zero energy. This result also holds for a wide class of scattering manifolds.
Keywords: Scattering theory, conormal, Lagrangian
