The role of one-pion exchange is examined in the deep-inelastic region for electron-nucleon scattering. Exclusive channels like πN, πΔ will contribute negligible, nonscaling contributions to σS. On the other hand, inclusive final states like N + "anything," where the detected final nucleon is slow in the lab system, afford the opportunity to experimentally determine the structure functions for electron-pion scattering provided the characteristic one-pion-exchange structure (dip or peak) is observed at small momentum transfer.
