Abstract
Abstract Inelastic electron-deuteron scattering has been calculated at backward angles for energy transfers up to 50 MeV and momentum transfers up to 60 fm −2 . Exchange currents from the pion, vector mesons and mixed ϱπγ and ωπγ were taken into account. The effect of the meson-nucleon form factor is studied, and various approximations of the mesonic currents are discussed. Baryon resonance configurations in the wave function have been used to calculate the Δ-resonance currents. We show that the effect from meson-nucleon form factors, the ϱπγ, ωπγ and Δ currents cancels almost exactly against the vector meson contribution at low momentum transfer. Thus the pure pionic current defines a reasonable choice. In the high momentum region this approximation breaks down.
