Angular distributions allow a separation of the contributions + from the two form factors. The distributions are presented for the + ​laboratory and the hadronic rest frame, and the advantages of different + ​coordinate systems are investigated. It is demonstrated that $Q^2$ values + up to 8 or even 9 GeV$^2$ are within reach. The Monte Carlo event + ​generator PHOKHARA is extended to nucleon final states, and results + are presented which include Next-to-Leading Order radiative corrections + from initial-state radiation. The impact of angular cuts on rates and + ​distributions is investigated and the relative importance of radiative + ​corrections is analysed. + ​ + |**H. Czyz, J. H. K"uhn, E. Nowak, G.
