The cross section of the process e+e- -> pi+pi- has been measured at the
CMD-2 detector in the 370-520 MeV center-of-mass (c.m.) energy range. A
systematic uncertainty of the measurement is 0.7 %. Using all CMD-2 data on the
pion form factor, the pion electromagnetic radius was calculated. The cross
section of muon pair production was also determined.
