Abstract
We consider a pair of Hamiltonians (H,H 0) on L 2(ℝn), where H 0 = p 2−x 2 is a Schrödinger operator with a repulsive potential, and H = H 0+V (x). We show that, under suitable assumptions on the decay of the electric potential, V is uniquely determined by the high energy limit of the scattering operator.
