摘要：

A relativistic meson exchange approach to the pion-nucleon interaction is developed using a three-dimensional relativistic two-body propagator and the results using different propagators compared. The relativistic approach is able to describe low-energy scattering up to 400 MeV above threshold, while preserving the soft-pion theorems. The different propagators give similar results, as the form factors necessary to get a fit suppress much of the multiple scattering.
