چکیده انگلیسی
The reaction e+eââίΠis investigated for energies close to the threshold. Specific emphasis is put on the role played by the interaction in the final ίΠsystem which is taken into account rigorously. For that interaction a variety of ίΠpotential models is employed that have been constructed for the analysis of the reaction p¯pâίΠin the past. The enhancement of the effective form factor for energies close to the ίΠthreshold, seen in pertinent experiments, is reproduced. Predictions for the Î electromagnetic form factors GM and GE in the timelike region and for spin-dependent observables such as spin-correlation parameters are presented.
