Solution of a Coupled Channel Inverse Scattering Problem at Fixed Energy by a Modified Newton-Sabatier Method.

Abstract

The modified Newton-Sabatier method is extended to the inverse scattering problem of coupled channels at fixed energy. The problem is solved for a system of coupled radial Schr{umlt o}dinger equations with a potential matrix independent of the angular momentum of the relative motion. The new method is applied to the example of two channels coupled by complex-valued square well potentials. {copyright} {ital 1996 The American Physical Society.}
