PWIA Extraction of the Neutron Magnetic Form Factor from Quasi-Elastic 3He(e,e') at Q^2 = 0.3 to 0.6 (GeV/c)^2

Abstract

A high precision measurement of the transverse spin-dependent asymmetry A_{T'} in ^3 vec{He}(vec{e},e') quasielastic scattering was performed in Hall A at Jefferson Lab at values of the squared four-momentum transfer, Q^2, between 0.1 and 0.6 (GeV/c)^2. A_{T'} is sensitive to the neutron magnetic form factor, G_M^n. Values of G_M^n at Q^2 = 0.1 and 0.2 (GeV/c)^2, extracted using Faddeev calculations, were reported previously. Here, we report the extraction of G_M^n for the remaining Q^2-values in the range from 0.3 to 0.6 (GeV/c)^2 using a Plane-Wave Impulse Approximation calculation. The results are in good agreement with recent precision data from experiments using a deuterium target.
