Abstract : Measurements of the ratio of the deuterontoproton electric form factors, G(E) sub d/G(E) sub p, were made from elastic electrondeuteron 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 neutronelectron interaction slope when relativistic corrections and FeshbachLomon deuteron wave functions are applied to the electrondeuteron 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 FeshbachLomon calculation.
