Abstract : It is shown that a usual MANDELSTAM representation completed with a suitable choice for pole terms and single dispersion integrals, obtained straightforwardly from unitarity using quantum electrodynamics and the resonance structure of the pion, provides a method to discuss electron-pion scattering on the same lines as strong interaction theory. The double spectral functions are constructed from a system of integral equations in a strip approximation, and corrections to the one-photon exchange amplitude are expressed by integrals over the imaginary part of the form factor in the annihilation channel.
