Abstract

The ratio of the electric to the magnetic form factor of the neutron, $g \equiv G_{En}/G_{Mn}$, was measured via recoil polarimetry (R.G. Arnold, C.E. Carlson, F. Gross, Phys. Rev. C 23, 363 (1981)) from the quasielastic ^2H $(\mathop{e}\limits^{\scriptstyle\to},e' \mathop{n}\limits^{\scriptstyle\to} )$ ^1H reaction at three values of Q² (viz, 0.45, 1.15, and 1.47 (GeV/c)²) in Hall C of the Thomas Jefferson National Accelerator Facility. The data reveal that G_En continues to follow the Galster parameterization up to Q ² = 1.15 (GeV/c)² and rises above the Galster parameterization at Q ² = 1.47 (GeV/c)².
