Measurements of differential cross sections for quasielastic electron-deuteron scattering e+d-->e+p+n have been made in which recoil protons were detected in coincidence with the scattered electrons. The ratios of the elastic electron-neutron to the electron-proton scattering cross sections are derived from the proton coincidence data. For comparison, these ratios are also determined from the scattered-electron momentum spectra using the peak and area methods. The theory developed by Renard, Tran Thanh Van, and LeBellac, which includes corrections for the final-state interactions, is found to explain the proton coincidence results. The present measurements, made at an electron scattering angle of 90° for four-momentum transfers of q^2 = 7, 10, 15, and 29 F^-2, and at 80° for q^2 = 45 F^-2, are combined with previous results to obtain the electromagnetic form factors of the neutron.
