  The process e+e- ->pi+pi- has been studied with the SND detector at VEPP-2M
e+e- collider in the vicinity of phi(1020) resonance. From the analysis of the
energy dependence of measured cross section the branching ratio
B(phi->pi+pi-)=(7.1+-1.1+-0.9)*10^{-5} and the phase psi_pi=-(34+-4+-3)degrees
of interference with the non-resonant pi+pi- production amplitude were
obtained.
