We develop a consistent approach to an inverse scattering problem for the Schrodinger equation with nonlocal potentials. The main result presented in this paper is that for the two-body scattering data, given the problem of reconstructing both the family of phase equivalent two-body wavefunctions and the corresponding family of phase equivalent half-off-shell t-matrices, is reduced to solving a regular integral equation. This equation may be regarded as a generalization of the Gel’fand-Levitan equation.

Starting from the general positioning of an inverse scattering problem for the Schrodinger equation with nonlocal potentials, we give a constructive description of the family of phase equivalent two-body potentials. It is shown that if the S-matrix Sl(k) is of a rational type in k then for a dense set of potentials our main integral equation comes to a system of second-order algebraic equations, and these potentials are of a separable form. This essentially resolves all computational problems when dealing with the nuclear few-body problems.

AbstractThis paper is concerned with the inverse scattering problem for the three-dimensional Maxwell equations in bi-anisotropic periodic structures. The inverse scattering problem aims to determine the shape of bi-anisotropic periodic scatterers from electromagnetic near-field data at a fixed frequency. The factorization method is studied as an analytical and numerical tool for solving the inverse problem. We provide a rigorous justification of the factorization method which results in the unique determination and a fast imaging algorithm for the periodic scatterer. Numerical examples for imaging three-dimensional periodic structures are presented to examine the efficiency of the method.
