Abstract

We report a measurement of the asymmetry in spin-dependent quasielastic scattering of longitudinally polarized electrons from a polarized 3He target. The neutron magnetic form factor GM^n has been extracted from the measured asymmetry based on recent PWIA calculations using spin-dependent spectral functions. Our determination of GM^n at Q^2=0.19 (GeV/c)^2 agrees with the dipole parametrization. This experiment represents the first measurement of the neutron magnetic form factor using spin-dependent electron scattering.
