Abstract
We saw that electroproduction experiments in the resonance region can, in principle, give information on (γ N N*)-transition form factors, the pion form factor Fπ, the neutron electric form factor G e n and on the axial nucleon form factor GA. At present, electroproduction is the only practical source of information on Fπ in the spacelike region and on the transition form factors. However, several difficulties are involved:
