[en] The search for the PHI → π⁺π^- decay is carried out. For this purpose processed are the events characterized by the collinear particle tracks and related to the e⁺e^- → e⁺e^-, e⁺e^- → μ⁺μ^-, e⁺e^- → π⁺π^- processes. Excitation curve of the PHI resonance is measured by scanning the energy interval from 1014 to 1026 MeV with a pitch of 0.5 MeV. By the maximum likelihood method, relative probability of the PHI → π⁺π^- decay is determined which turns out to be smaller than 6.6x10^-4 at the 0.95 c.l. The pion formfactor averaged over the experimental energy is equal to to 2.6+-0.2
