Abstract

The beam-recoil double polarization Ph x0 and Ph z0 and the recoil polarization Py0 were measured for the first time for the pe~ ; e0p~ reaction at a four-momentum transfer of Q2 0:1 GeV2=c2 and a center of mass production angle of 120 at the Mainz Microtron MAMI-C.With a center of mass energy range of 1500 MeV.
