Magnetic Form Factor of the Neutron at 600 Mev

Abstract

The study of electrons scattered inelastically from the deuteron has been extended to 600 Mev. Data at 500 Mev were reported in an earlier paper. Results are presented for seven scattering angles between 45° and 135°. A comparison of the deuteron's cross section at these angles with the corresponding free proton cross sections permits a determination of the form factor associated with the magnetic moment distribution of the neutron. Two different methods of analyzing the data are described, and the rms radius of the neutron for an exponential density distribution of the magnetic cloud can be shown to lie between the limits of 0.75×${10}^{-13\mathrm{}}$ cm and 0.95×${10}^{-13\mathrm{}}$ cm. The rms radius of the neutron may be taken to be (0.80±0.10)×${10}^{-13\mathrm{}}$ cm and is very close to the value found for an exponential model of the magnetic cloud in the proton.
