ResumoData on π+-electroproduction off protons are analysed in a generalized Born term model, where the off-shell nucleon form factor F1(k2) is allowed to differ from its on-shell value. The longitudinal-transverse interference cross section is sensitive to the ratio of the nucleon form factor to the pion form factor, and the data require this ratio to be larger than one. The resulting transverse cross section, integrated over a small t-interval, follows the slow decrease of the total inelastic cross section as a function of the photon mass squared.
