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
