 +   <hidden TTP04-05  Nucleon form factors, B-meson factories and the radiative return > The feasibility of a measurement of the electric and magnetic nucleon 
 + form factors at $B$-meson factories through the radiative return is 
 + studied. 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.
