A coupled channel theory of resonances has been formulated within the propagator approach of many‐body theory and applied to the 1s3s 2 resonance of e ‐helium scattering. This system has previously been studied both experimentally and theoretically. Our results for the width of the resonance agree well with these earlier findings. © 1994 John Wiley & Sons, Inc.
