TENSOR POLARIZATION IN ELASTIC ELECTRON-DEUTERON SCATTERING IN THE MOMENTUM-TRANSFER RANGE -LESS-THAN-OR-EQUAL-TO-Q-LESS-THAN-OR-EQUAL-TO-4.6 FM(-1)

The tensor polarization of the recoil deuteron in elastic electron-deu teron scattering has been measured at the Bates Linear Accelerator Cen ter at three values of four-momentum transfer, Q = 3.78, 4.22, and 4.6 2 fm-1, corresponding to incident electron energies of 653, 755, and 8 53 MeV. The scattered electrons and the recoil deuterons were detected in coincidence. The recoil deuterons were transported to a liquid hyd rogen target to undergo a second scattering. The angular distribution of the d-p scattering was measured using a polarimeter. The polarimete r was calibrated in an auxiliary experiment using a polarized deuteron beam at the Laboratoire National Saturne. A Monte Carlo procedure was used to generate interpolated calibration data because the energy spr ead in the deuteron energies in the Bates experiment spanned the range of deuteron energies in the calibration experiment. The extracted Val ues of t20 are compared to predictions of different theoretical models of the electromagnetic form factors of the deuteron: nonrelativistic and relativistic nucleon-meson dynamics, Skyrme model, quark models, a nd perturbative quantum chromodynamics. Along with the world data on t he structure functions A(Q) and B(Q), they are used to separate the ch arge monopole and charge quadrupole form factors of the deuteron. A no de in the charge monopole form factor is observed at Q = 4.39 +/- 0.16 fm-1.
