The S-wave e (as Fe/sup 59 - e (as Fe/sup 59 scattering amplitude is calculated by using the chain approximation from the unrenormalizable interaction Lagrangian that gives rise to the same P-wave scattering amplitude as obtained by Frazer and Fulco from the dispersion relation. It is found that the S-wave amplitude contains two additional parameters. This appearance of new parameters is inevitable since the interaction is unrenormalizable. The connection of our method of solution with that of the dispersion relation is also discussed. The calculation gives rise to a low-energy resonance in the I = 0 state that may be identified as the resonance observed by Booth. (auth)
