Precise measurement of the neutron magnetic form factor G(M)n in the few-GeV2 region

Phys Rev Lett. 2009 May 15;102(19):192001. doi: 10.1103/PhysRevLett.102.192001. Epub 2009 May 12.


The neutron elastic magnetic form factor was extracted from quasielastic electron scattering on deuterium over the range Q;{2}=1.0-4.8 GeV2 with the CLAS detector at Jefferson Lab. High precision was achieved with a ratio technique and a simultaneous in situ calibration of the neutron detection efficiency. Neutrons were detected with electromagnetic calorimeters and time-of-flight scintillators at two beam energies. The dipole parametrization gives a good description of the data.
