AbstractAn amplitude-phase formula for the S matrix using two Milne solutions and the regular Schr¨odinger solution is derived. The formula is particularly useful in the analysis of Regge poles located far out in the complex -plane, particularly for discontinuous scattering potentials. Numerical applications for an attractive square-well potential and an inverse-power potential ~r^(-4) are presented.
