Due to the inconsistency in the results of the GEp/Gmp ratio of the proton,as extracted from the Rosenbluth and recoil polarization techniques, highprecision measurements of the e-p elastic scattering cross sections were madeat Q^2 = 2.64, 3.20, and 4.10 GeV^2. Protons were detected, in contrast toprevious measurements where the scattered electrons were detected, whichdramatically decreased epsilon-dependent systematic uncertainties andcorrections. A single spectrometer measured the scattered protons of interestwhile simultaneous measurements at Q^2 = 0.5 GeV^2 were carried out usinganother spectrometer which served as a luminosity monitor in order to removeany uncertainties due to beam charge and target density fluctuations. Theabsolute uncertainty in the measured cross sections is \approx 3% for bothspectrometers and with relative uncertainties, random and slope, below 1% forthe higher Q^2 protons, and below 1% random and 6% slope for the monitorspectrometer. The extracted electric and magnetic form factors were determinedto 4%-7% for GEp and 1.5% for GMp. The ratio GEp/Gmp was determined to 4%-7%and showed mu_p GEp/GMp \approx 1.0. The results of this work are in agreementwith the previous Rosenbluth data and inconsistent with high-Q^2 recoilpolarization results, implying a systematic difference between the twotechniques.
