Excerpt from The Determination of the Scattering Potential From the Spectral Measure Function In the present paper we shall show how, in many cases, the potential can be obtained from the spectral measure function if we specify the asymptotic behavior of the eigenfunctions of the total Hamiltonian. The procedure which we shall use will be very general and more abstract than those used previously. We shall assume some very general properties of the unperturbed Hamiltonians instead of restricting ourselves to kinetic energy Operators. Furthermore we shall not require that the perturbation be diagonal in a Specific representa tion. It is hoped that in the future the results which we present here can be used to infer potentials from scattering Operators in an abstract way.
