Abstract

A phase-shift analysis technique for two-channel scattering has been studied. The inputs to the study were the experimental differential cross sections and the unitarity condition was then used to extract the phase of the scattering amplitudes. A Newton iterative method based upon Frechet derivatives gave convergent results. The method was tested by using both simulated data and theoretical calculations for electron-helium scattering.
