Sub-femtoscopic Rutherford Scattering

Lepton-hadron interactions at the Fermi energy scale probe the structure of hadrons, the structure of the electro-weak interaction, and the structure of the hadronic interaction at the sub-femtoscopic distance scale. After setting a context in such terms with well-known, encyclopaedic, measurements of deeply inelastic, posit(elect)ron-proton scattering of centre-of mass energy of ~100π GeV, the first steps in identifying in data the essential features which characterise sub-femtoscopic Rutherford scattering are reported.
