Scattering and inverse scattering for multipoint potentials at high energies

We consider the Schrödinger equation with a multipoint potential of Bethe-Peierls-Thomas-Fermi type. For this singular potential, we develop scattering and inverse scattering at high energies. In particular, in this framework, our results include analogs of the “regular” Born-Faddeev formula for the scattering amplitude and analogs of related “regular” inverse scattering reconstructions at high energies. Related results for scattering solutions at high energies are also presented.
