Abstract: (APS)
A study of the factors which govern a precise determination of the S- and P-wave pion-nucleon scattering lengths using phenomenological energy-dependent partial-wave analyses is made. The nuclear scattering lengths obtained result from rapidly convergent effective-range expansions and are shown to be insensitive to the energy cutoff. These phenomenological values are in general agreement with theoretical treatments.
