Electromagnetic proton form factors at squared four-momentum transfers between 1 and 3 (GeV/ c) 2

Abstract

Electron-proton elastic scattering cross sections have been measured at four-momentum transfers between 1.0 and 3.0 (GeV/ c) 2 and at electron scattering angles between 10° and 20° and at about 86° in the laboratory. The proton electromagnetic form factors G E and G M were determined. The results indicate that G E( q 2) decreases faster with increasing q 2 than G M( q 2).
