Exploring the gamma* p --> Delta(1232) Transition at Low Q2 Using CLAS
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.
