Normal spin asymmetries in the A4 experiment — •David Balaguer Rios — Institut fuer Kernphysik, Mainz, Deutschland

At the MAMI facilities the A4 Collaboration has measured the normal spin asymmetries in the elastic and quasielastic scattering of electrons on proton and deuteron, respectively, to have access to the imaginary part of the two-photon exchange amplitude. Here we present the measurements for the energies of 210, 315 and 420 MeV at backward angles and compare them with the model calculations.
