Abstract

The neutron elastic magnetic form factor GnMhas been extracted from quasielastic scattering from deuterium in the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab. The kinematic coverage of the measurement is continuous over a broad range, extending from below 1 (GeV/c)2to nearly 5 (GeV/c)2in four-momentum transfer squared. High precision was achieved by employing a ratio technique in which many uncertainties cancel, and by a simultaneous in-situ calibration of the neutron detection efficiency, the largest correction to the data. Neutrons were detected using electromagnetic calorimeters and time-of-flight scintillators. Data were taken at two different electron beam energies, allowing up to four semi-independent measurements of GnMto be made. The dipole parameterization is found to provide a good description of the data for Q2> 1 (GeV/c)2.
