Separated longitudinal and transverse structure functions for the reaction 1H(e,e(')pi(+))n were measured in the momentum transfer region Q2 = 0.6--1.6 (GeV/c)(2) at a value of the invariant mass W = 1.95 GeV. New values for the pion charge form factor were extracted from the longitudinal cross section by using a recently developed Regge model. The results(More)
The charged pion form factor, F π (Q 2), is an important quantity that can be used to advance our knowledge of hadronic structure. However, the extraction of F π from data requires a model of the 1 H(e, e π +)n reaction and thus is inherently model dependent. Therefore, a detailed description of the extraction of the charged pion form factor from(More)
We report measurements of cross sections for the reaction p(e,e ′ K +)Y, for both the Λ and Σ 0 hyperon states, at an invariant mass of W =1.84 GeV and four-momentum transfers 0.5 < Q 2 < 2 (GeV/c) 2. Data were taken for three values of virtual photon polarization ǫ, allowing the decomposition of the cross sections into longitudinal and transverse(More)
—Results from an instrument-level spectral characterization of the 21-channel High Resolution Dynamics Limb Sounder (HIRDLS) flight instrument will be presented. These data were obtained during the prelaunch calibration of HIRDLS at the University of Oxford (fall 2002). A monochromator, equipped with a controllable diffraction grating, was used to produce(More)
The study of exclusive π(±) electroproduction on the nucleon, including separation of the various structure functions, is of interest for a number of reasons. The ratio RL=σL(π-)/σL(π+) is sensitive to isoscalar contamination to the dominant isovector pion exchange amplitude, which is the basis for the determination of the charged pion form factor from(More)
We report new measurements of the ratio of the electric form factor to the magnetic form factor of the neutron, G(n)(E)/G(n)(M), obtained via recoil polarimetry from the quasielastic 2H(e-->,e(')n-->)1H reaction at Q2 values of 0.45, 1.13, and 1.45 (GeV/c)(2) with relative statistical uncertainties of 7.6% and 8.4% at the two higher Q2 points, which points(More)
We report the first measurement using a solid polarized target of the neutron electric form factor G(n)(E) via d-->(e-->,e(')n)p. G(n)(E) was determined from the beam-target asymmetry in the scattering of longitudinally polarized electrons from polarized deuterated ammonia ( 15ND3). The measurement was performed in Hall C at Thomas Jefferson National(More)
