Tensor polarization measurement in elastic electron-deuteron scattering at large momentum transfer

摘要

The three tensor polarization components (t_20, t_21 and t_22)of the recoil deuteron in elastic electron-deuteron scattering have been measured in the range of 4-momentum transfer Q = 4.1-6.8 fm~-1. The experiment was performed with the multi-GeV, high intensity electron beam available at the Jefferson Laboratory and using the tensor deuteron polarimeter POLDER. These new data are used to separate the charge Gc and quadrupole GQ Form factors at large momentum transfer and provide additional constraints On theoretical models.
