Abstract
We investigate the effect of the electric formfactor on dilepton produ ction off pp-collisions. In the model we use, the formfactor is separa ted in a pion-cloud contribution and a vector meson dominance part. We find that the dilepton spectrum is hardly affected by the pion-cloud part, but significantly by the VMD contribution. We point out that dat a with sufficient resolution would provide a crucial test of the valid ity of VMD for the nucleon formfactor in the timelike region.
