OSTI ID:839141
New measurements of the electroproduction of the Delta (1232) resonance through the p(e, e'p) pi0 and p({rvec e}, e'p) pi0 reactions have been performed. The data were taken with the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab using polarized and unpolarized incident electron beam. Cross sections were measured simultaneously with continuous coverage over a large range of four-momentum transfer Q2=(0.3-1.2 GeV2). Decay angular distributions in the p pi0 center-of-mass were obtained over the full range of cos thetac.m. and phi c.m.. The high statistical accuracy of this data set is expected to provide strong constraints on dynamic models of the N --> Delta transition form factors.
