I'm already aware that deep inelastic scattering, when an electron of high energy is scattered from a proton, shows us that the proton consists of point-like particles (quarks). However, what does elastic electron proton scattering tell us about the proton? Presumably elastic proton scattering is when the electron has low energy, so just recoils with energy/momentum conserved. And so it just suggests that the proton is a single structure. But I've been asked what information this process gives us about the proton structure. Does it tell us anything else?
Thanks
