Pi0 electroproduction in the Delta(1232) region at MAMI
Abstract
The extraction of the Coulomb quadrupole to magnetic dipole ratio from a p(epol,e'ppol)pi0 measurement is discussed. Preliminary results from further asymmetry measurements with polarized and unpolarized electron beam indicate that the imaginary background is well under control in the MAID2000 parameterization, but not the real (Born-) amplitudes.
