【 摘 要 】

Precision measurements of the p(e, e(prime) p)pi0 reaction were performed using the CEBAF Large Acceptance Spectrometer (CLAS) in the range of photon invariant momentum transfer Q2 = 0.16 0.36 GeV2. Fits to the data using both a Unitary Isobar Model and the Sato-Lee dynamical model are used to estimate the 'dressed' and 'bare' electromagnetic couplings for the magnetic and quadrupole gamma* p --> Delta(1232) transition form factors.
