Abstract

Elastic electron deuteron scattering has been measured at the Bonn 2.5 GeV electron-synchrotron using a tensor polarised ND3 target. The scattered electrons and deuterons were detected in coincidence by two magnetic spectrometers. Data were taken at an average value of four momentum transfer of Q2 = 0.495 (GeV/c)2 in order to separate the electric monopole and quadrupole form factors of the deuteron. To have a sufficient control of systematic effects, both polarized and unpolarised cross sections were measured with an identical experimental set up. In the ratio R BXP =d σ pol /d σ unp systematic effects are expected to cancel. This ratio R BXP is related to the theoretical polarized cross section d σ T where the spin quantization axis for the deuterons is orientated in the ed-scattering plane, perpendicular to the virtual photon direction. Our final result for the corresponding recoil tensor polarization is t20=−2.01±1.13.
