It is shown that a resonance of suitable position and width in the J = 1. I = 1 state of the pion-pion system can bring the dispersion-theoretic calculation of the isotopicvector part of the nucleon electromagnetic structure into agreement with experiment. The calculation of the isotopic-vector part of the nucleon form factors involves in first approximation the pion form factor and the matrix element for the production by two pions of a nucleonantinucleon pair. For the pion form factor a semiphenomenological solution based on the work of Chew and Mandelstam and involving two parameters related to the position and width of the resonance was used. (auth)
