Abstract

We report the results of a new Rosenbluth measurement of the proton electromagnetic form factors at Q² values of 2.64, 3.20, and 4.10 GeV². Cross sections were determined by detecting the recoiling proton, in contrast to previous measurements which detected the scattered electron. Cross sections were determined to 3%, with relative uncertainties below 1%. The ratio μ_pG_E/G_M was determined to 4%-8% and showed μ_pG_E/G_M ≈ 1. These results are consistent with, and much more precise than, previous Rosenbluth extractions. They are inconsistent with recent polarization transfer measurements of similar precision, implying a systematic difference between the techniques.
