Abstract: (arXiv)

We describe the method of measuring the integrated luminosity of the

e^+e^-

collider DA

\Phi

NE, the Frascati

\phi-

factory. The measurement is done with the KLOE detector selecting large angle Bhabha scattering events and normalizing them to the effective cross section. The

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

cross section is calculated using different event generators which account for the

O(\alpha)

radiative initial and final state corrections, and the

\phi

resonance contribution. The accuracy of the measurement is 0.6%, where 0.3% comes from systematic errors related to the event counting and 0.5% from theoretical evaluations of the cross section.
