Measurement of the magnetic form factor of the neutron
Abstract
The 2H(e,e'n)1H quasielastic cross section was measured at Q2 values of 0.109, 0.176, and 0.255 (GeV/c)2. The neutron detection efficiency was determined by the associated particle technique with the 2H(γ,pn) reaction for each of the three neutron kinetic energies. These 2H(e,e'n) measurements of the coincidence cross sections are the first at low Q2. The cross sections are sensitive primarily to the neutron magnetic form factor GnM at these kinematics. The extracted GnM values have smaller uncertainties than previous data and are consistent with the dipole parametrization at the two higher momentum transfers; at the lowest momentum transfer, the value of GnM is ~10% higher than the dipole value.
