Nucleon-antinucleon optical potential, which explains the experimental data for the processes e+e^\ensuremath-\ensuremath→pp and e+e^\ensuremath-\ensuremath→pions near the threshold of pp pair production, is suggested. To obtain this potential, we have used the available experimental data for pp scattering, pp pair production in e+e^\ensuremath- annihilation, and the ratio of electromagnetic form factors of a proton in the timelike region. It turns out that final-state interaction via the optical potential allows one to reproduce the available experimental data with good accuracy. Our results for the cross sections of the e+e^\ensuremath-\ensuremath→6\ensuremathπ process near the threshold of pp pair production are in agreement with the recent experiments.
