Measurements of the Electric Form Factor of the Neutron at High Momentum Transfer

The electric and magnetic form factors of the micleon provide experimental access to the underlying charge and magnetic moment distributions of quarks. We have measured the electric form factor of the neutron at four kinematic points between 1.2 and 3.5 GeV(2) in Hall A at Jefferson Lab. This more t...

Description
Summary:The electric and magnetic form factors of the micleon provide experimental access to the underlying charge and magnetic moment distributions of quarks. We have measured the electric form factor of the neutron at four kinematic points between 1.2 and 3.5 GeV(2) in Hall A at Jefferson Lab. This more than doubles the momentum transfer region for which this quantity has previously been measured, providing new information on the structure of the neutron. Preliminary results for G(E)(n) at Q(2) = 1.7,2.5, and 3.5 GeV(2) were presented and were compared with QCD-based models and phenomenological approaches.
