Abstract: The cross section for the process e ⁺ e ⁻ → π⁺π⁻ is measured in the c.m. energy range 1.04—1.38 GeV by analyzing 995 000 selected collinear events including 860000 e ⁺ e ⁻ events, 82000 μ⁺μ⁻ events, and 33000 π⁺π⁻ events. The systematic and statistical errors of measuring the pion form factor are equal to 1.2–4.2 and 5–13%, respectively.
