Title Neutron Magnetic Form Factor from the Ratio of quasi-elastic Electron-Neutron to Electron-Proton Scattering in Deuterium
Abstract The neutron magnetic form factor GnM has been extracted from the ratio of quasielastic e-n to e-p scattering from a deuterium target using the CLAS detector. The measurement covers the range 0.5 to 4.5 (GeV/c)2 in four-momentum transfer squared. High precision was achieved by use of the ratio technique, with which many uncertainties cancel. A dual-cell target was used, featuring a deuterium cell and a hydrogen cell, which allowed a simultaneous in-situ calibration of the neutron detection efficiency. Neutrons were detected using the CLAS Time-of-Flight system and the Forward Electromagnetic Calorimeter. Data was taken at two different electron beam energies, allowing up to four semi-independent measurements of GnM to be made at each value of Q2. The data is compared to previous measurements, and with several theoretical and phenomenological models. It is found that for Q2 > 1 (GeV/c)2 the standard dipole parametrization gives a good representation of the data over a wide range of Q2.
