Abstract

Quadrupole amplitudes in the γ*N → Δ transition are associated with the issue of nucleon deformation. A search for these small amplitudes has been the focus of a series of measurements undertaken at Bates/MIT by the OOPS Collaboration. We report on results from H(e,e′ p)π0 data obtained at Q2 = 0.070 (GeV/c)2 and invariant mass of W = 1155 MeV using the out-of-plane detection technique with the OOPS spectrometers. The σLT and σT + σL response functions were isolated. These results, along with those of previous measurements at W = 1172 MeV and Q2 = 0.127 (GeV/c)2, aim in elucidating the interplay between resonant and nonresonant amplitudes.
