T-Matrix Analyticity Using Fredholm Theory

Abstract

The behavior of the Regge pole residues for the T matrix analyzed into partial waves is studied as a function of E for scattering from a Yukawa potential. Using a variational formulation of Fredholm theory, we explicitly show that the residues on the energy shell have no branch cuts in the left-hand E plane.
