Deep inelastic scattering of charged leptons.
The concept of a model based on the hypothesis of smooth extrapolation rather than explicit dynamical speculation is expounded. The existing body of successful applications is extended to the longitudinal cross section in deep inelastic scattering, and predictions are made for the asymmetry in scattering of polarized electrons on polarized protons.
