Scattering formulation based on an amplitude-independent variational principle

Abstract

In this paper we reply to the preceding Comment by Abdel-Raouf concerning several features of an amplitude-independent variational principle which we have recently proposed. The most substantive discussion concerns the nature of the singularities which can arise in one of these variational principles. The specific variational principle involved contains the Hamiltonian and not the Green's-function operator.
