Abstract
The ratio of the electric to the magnetic form factor of the neutron, g = GEn/GMn, was measured via recoil polarimetry (R.G. Arnold, C.E. Carlson, F. Gross, Phys. Rev. C 23, 363 (1981)) from the quasielastic 2H([This symbol cannot be presented in ASCII format], e′ [This symbol cannot be presented in ASCII format])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 Q = 1.15 (GeV/c)2 and rises above the Galster parameterization at Q 2 = 1.47 (GeV/c)2. [ABSTRACT FROM AUTHOR]
