چکیده

Tensor polarization observables ( t(20), t(21), and t(22)) have been measured in elastic electron-deuteron scattering for six values of momentum transfer between 0.66 and 1.7 (GeV/c)(2). The experiment was performed at the Jefferson Laboratory in Hall C using the electron High Momentum Spectrometer, a specially designed deuteron magnetic channel and the recoil deuteron polarimeter POLDER. The new data determine to much larger Q2 the deuteron charge form factors G(C) and G(Q). They are in good agreement with relativistic calculations and disagree with perturbative QCD predictions.

Tensor Polarization of the Deuteron at High Momentum Transfer in Elastic

The measurement of deuteron tensor polarization using (e, d) elastic scattering was performed in Hall C, Jefferson Lab by the t20 collaboration at four-momentum transfers of 4.10, 4.46, 5.08, 5.48, 6.23 and 6.65 fm 1 . The scattered electrons were detected by the High Momentum Spectrometer, and a specially designed magnetic channel was used to detect deuterons in coincidence. The polarization o...

The tensor polarization of the recoil deuteron in elastic electron-deuteron scattering has been measured at the Bates Linear Accelerator Center at three values of four-momentum transfer, Q = 3.78, 4.22, and 4.62 fm-', corresponding to incident electron energies of 653, 755, and 853 MeV. The scattered electrons and the recoil deuterons were detected in coincidence. The recoil deuterons were tran...

Measurement of elastic electron-neutron scattering and inelastic electron-deuteron scattering cross sections at high momentum transfer.

We have measured inelastic electron-deuteron, electron-proton, and electron-aluminum cross sections at 10' in the kinematic region between-elastic deuteron scattering and the second resonance region at six beam energies between 9.8 and 21 GeV. The elastic electron-neutron cross section was extracted from the quasi-elastic data at Q2 = 2.5, 4.0, 6.0, 8.0 and 10.0 (GeV/c)'. The ratio of elastic c...

Radiative corrections to deep – inelastic ed − scattering

The model–independent radiative corrections to deep–inelastic scattering of unpolarized electron beam off the tensor polarized deuteron target have been considered. The contribution to the radiative corrections due to the hard–photon emission from the elastic electron–deuteron scattering (the so–called elastic radiative tail) is also investigated. The calculation is based on the covariant param...

Two - Photon Exchange in Electron - Deuteron Scattering

We show that multiple scattering of the electron (i.e., two-photon exchange) in electron-deuteron elastic scattering leads to a small component in the cross section, which decreases very slowly with momentum transfer, and may dominate the cross section at high momentum transfer.
