Abstract

We report precision 1H(e,e^′π⁺)n measurements in the Δ(1232) resonance at Q2=0.127(GeV/c)2 obtained at the MIT-Bates out-of-plane scattering facility. These are the lowest, but nonzero, Q2 measurements in the π⁺ channel. The data offer tests of the theoretical calculations, particularly of the background amplitude contributions. The chiral effective field theory and Sato-Lee model calculations are not in agreement with this experiment.
