Sažetak
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<W <1550 MeV the region of the S111535 and D131520 resonance was covered. Theresults are discussed in the framework of a phenomenological isobar model (Eta-MAID). While Ph x0 and Ph z0 are in good agreement with the model, Py0 shows a significant deviation, consistent with existing photoproduction data on the polarized-target asymmetry.
