Description
In this talk, a new experimental method based on initial-state
radiation (ISR) in e-p scattering will be presented, in which the
radiative tail of the elastic e-p peak is used to extract information on the
proton charge form factor (G_E^p) at extremely small Q^2. The ISR
technique was validated in a dedicated experiment using the
spectrometers of the A1-Collaboration at the Mainz Microtron
(MAMI). This provided first measurements of
G_E^{p} for 0.001<Q^2 < 0.004 (GeV/c)^2.
