Systematics ofπNscattering in chiral soliton models

We study the spin and isospin structure of pion-nucleon scattering amplitudes in the class of models, including the Skyrme model, in which the nucleon arises as a soliton built of pion fields. We derive general linear relations among partialwave amplitudes for the processes TN + TN and TN + TA and show that these relations are in reasonably good agreement with experiment.
