Tensor polarization observables (t20, t21 and t22) 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 HMS Spectrometer, a specially designed deuteron magnetic channel and the recoil deuteron polarimeter POLDER. The new data determine to much larger Q^2 the deuteron charge form factors G_C and G_Q. They are in good agreement with relativistic calculations and disagree with pQCD predictions.

DEUTERON A(Q**2) STRUCTURE FUNCTION AND THE NEUTRON ELECTRIC FORM-FACTOR

We have measured the deuteron A ( Q 2 ) structure function in the momentum transfer region between 1 and 18 fm −2 . The accuracy of the data ranges from 2 to 6%. These measurements allow a sensitive test of theoretical predictions. We find that meson-exchange currents and relativistic corrections significantly improve the agreement between experiment and theory. We investigate the sensitivity of A ( Q 2 ) to the nucleon-nucleon interaction and to the neutron electric form factor G E n ( Q 2 ). Our analysis shows that G E n ( Q 2 ) can be extracted from these data with a significantly improved accuracy. The model dependence of this analysis is discussed.

Electrodisintegration of the Deuteron Around q2=3.5 F-2

We have measured the absolute cross sections of the electron-deuteron scattering at q2=3.5 F−2 and obtained the complete inelastic spectrum. Three points for each spectrum are given with a 4% accuracy. The scattering angles, 60° and 130°, were chosen to allow the separation between electric and magnetic scattering. Calculations of radiative corrections were made in order to permit the comparison of the spectra with the inelastic-scattering theories.
