Description

Hadron electromagnetic form factors of hadrons in the time-like region at the boundary of the physical region is considered. The energy behaviour of the form factor is shown to be dominantely determined by the strong hadron-antihadron interaction. The scattering length imaginary part for $p-\bar{p}$, $Λ-\barΛ$, $Σ^0-\bar{Σ^0}$ are evaluated. We propose experiments to extract the information on the nearthreshold baryon-antibaryon interaction by using of hadron form foctors.
