Abstract : Measurements of the ratio of the deuteron-to-proton electric form factors, G(E) sub d/G(E) sub p, were made from elastic electron-deuteron scattering to a precision of approximately 1% for the range of momentum transfers, 0.10 or = q squared or = 0.8 f super(-2), and for electron scattering angles of 45 degrees and 120 degrees. It was found that within experimental errors the slope as obtained from the ratio G(E) sub n/G(E) sub p agrees with the extrapolated thermal neutron-electron interaction slope when relativistic corrections and Feshbach-Lomon deuteron wave functions are applied to the electron-deuteron scattering results. The deuteron radius was found to be 1.95 plus or minus 0.02 f, which agrees with the radius predicted by the Feshbach-Lomon calculation.
