摘要：

Low-energy pion-nucleon scattering phase shifts have been calculated using a model which includes only N, N*, ρ, and ε intermediate states. This remarkably simple model yields good agreement with phase shifts determined from experimental data. There are two adjustable parameters in the model. The even s-wave scattering length fixes one of these, and the other is determined by the ρ-nucleon magnetic moment coupling. The phase shifts are not sensitive to the choice of this coupling. © 1969 The American Physical Society.
