N2 - Stationary target measurements of the nucleon form factors have been performed with high precision down to Q2 of ∼ 0.01 GeV 2 for protons (GEp) and down to ∼ 0.1 GeV2 for neutrons (GMn). Conventional extraction using cross section and polarization measurement cannot be extended to very low values of Q2 due to inherent experimental limitations. We present a proposal for a new approach to a measurement, using colliding beams, which will extend the range of possible measurement at low Q2 by several orders of magnitude over stationary target limits.
