Measurement of Hadronic Cross Section at Kloe

In the fixed energy environment of the $e^{+}e^{-}$ collider DA$\Phi$NE, KLOE can measure the cross section of the process $e^{+}e^{-} \to hadrons$ as a function of the hadronic system energy using the radiative return method. At energies below 1 GeV, $e^{+}e^{-} \to \rho \to \pi^{+}\pi^{-}$ is the dominating hadronic process. We report here on the status of the analysis of the process $e^{+}e^{-} \to \pi^{+}\pi^{-}\gamma$. Some preliminary results on the invariant mass spectrum of the two pion system, obtained from the analysis of 22.6 pb$^{-1}$, are presented.
