摘要：

Pion-nucleon scattering lengths have been calculated using a model in which N, N*, ρ, and ε exchanges are assumed to dominate the low-energy pion-nucleon interaction. This simple model yields remarkably good agreement with the experimental s- and p-wave scattering lengths. We find that the coupling of the ε meson to the nucleon is consistent with estimates made using chiral symmetry and current algebra. © 1969 The American Physical Society.
