Abstract

The electron excitation of nucleon resonances is discussed both from the theoretical and from the experimental point of view. This discussion is based on a phenomenological approach that employs the conservation of the electromagnetic and vector-meson hadronic currents and the requirements of limiting chiral invariance. For the electron excitation of J(pi) = 1/2(+/-), 3/2(-/+), 5/2(+/-),... nucleon resonances, the structure functions are definedin terms of Sachs transition form factors. The resulting resonance structure functions for l + N --> l + R processes are used in parametrizing smooth(background) structure functions for l + N --> l + X inelastic scattering.
