Abstract:

We have measured the cross section

\sigma(e^+e^-\to \pi^+\pi^- \gamma)

at an energy

W=m_\phi=1.02

GeV with the KLOE detector at the electron-positron collider DA

\Phi

NE. From the dependence of the cross section on the invariant mass of the two-pion system, we extract

\sigma(e^+e^-\to \pi^+\pi^-)

for the mass range

0.35<s<0.95

GeV

^2

. From this result, we calculate the pion form factor and the hadronic contribution to the muon anomaly,

a_\mu

.
