Abstract

Electron-proton elastic scattering cross sections have been measured to determine the proton electromagnetic form factors at squared four-momentum transfers q2 between 10 and 50 fm−2. At these values of q2 we measured angular distributions between 25° and 110° and in addition at 25° and 35° cross sections for q2 from 2 to 20 fm−2 using the external electron beam of the Bonn 2.5 GeV electron synchrotron. Our results confirm deviations from the scaling law.
