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 GEn continues to follow the Galster parameterization up to Q2 = 1.15 (GeV/c)2 and rises above the Galster parameterization at Q2 = 1.47 (GeV/c)2.

Abstract

We report new measurements of the ratio of the electric form factor to the magnetic form factor of the neutron, ${G}_{E}^{n}/{G}_{M}^{n}$, obtained via recoil polarimetry from the quasielastic $^{2}\mathrm{H}(\stackrel{\ensuremath{\rightarrow}}{e},{e}^{\ensuremath{'}}\stackrel{\ensuremath{\rightarrow}}{n})^{1}\mathrm{H}$ reaction at ${Q}^{2}$ values of 0.45, 1.13, and $1.45\text{ }(\mathrm{G}\mathrm{e}\mathrm{V}/c{)}^{2}$ with relative statistical uncertainties of $7.6%$ and $8.4%$ at the two higher ${Q}^{2}$ points, which points have never been achieved in polarization measurements.
