“…Contributions to the previous world data which are noted here are the following. At lower Q 2 data have been obtained by the MAMI (Mainzer Microtron) [53,54,55,56,57], ELSA (University of Bonn) [58], LEGS (Brookhaven) collaboration [59,60] and the BATES (MIT) collaboration [61]. The Jefferson Laboratory spectrometer Hall A [62] has also made a significant contribution to the question of the structure of the N → ∆ transition.…”

The process ep → epπ 0 has been measured at Q 2 = 6.4 and 7.7 (GeV/c 2 ) 2 in Jefferson Lab's Hall C. Unpolarized differential cross sections are reported in the virtual photon-proton center of mass frame considering the process γ * p → pπ 0 . Various details relating to the background subtractions, radiative corrections and systematic errors are discussed. The usefulness of the data with regard to the measurement of the electromagnetic properties of the well known ∆(1232) resonance is covered in detail. Specifically considered are the electromagnetic and scalar-magnetic ratios REM and RSM along with the magnetic transition form factor G * M . It is found that the rapid fall off of the ∆(1232) contribution continues into this region of momentum transfer and that other resonances may be making important contributions in this region.
