Reconstruction of the phase shifts as functions of energy using bound-state energies and low- energy scattering data

Abstract

A procedure allowing to incorporate available information about scattering and bound states of a given system and use it as in input to represent phase shifts quite accurately in a region of momenta considerably broader than the region in which input phase shifts lie was proposed. As such, additional information making such a representation possible was provided by the known bound states. Account of the bound states in the framework of the present procedure may lead to substantial improvement in representing the correct phase shifts as functions of energy. Show more
