Scattering for 1D Schrödinger equation with energy-dependent potentials and the recovery of the potential from the reflection coefficient. (English) Zbl 1050.81706

Summary: We consider the 1D Schrödinger equation with a potential proportional to energy. When the spatial part of the potential is twice continuously differentiable, is less than 1 everywhere, and satisfies a certain integrability condition, we compute the scattering matrix. For the same class of potentials, under the further assumption that the potential is non-negative, we obtain the potential from one of the reflection coefficients.
