The reduced cross sections for ep, deep inelastic scattering have been measured with the ZEUS detector at HERA at three different centre-of-mass energies, 318, 251 and 225 GeV. From the cross sections, measured double differentially in Bjorken x and the virtuality, Q(2), the proton structure (f)unctions F-L and F-2 have been extracted in the region 5 x 10(-4) < x < 0.007 and 20 < Q(2) < 130 GeV2.

Abstract
The reduced cross sections for ep, deep inelastic scattering have been measured with the ZEUS detector at HERA at three different centre-of-mass energies, 318, 251 and 225 GeV. From the cross sections, measured double differentially in Bjorken x and the virtuality, Q(2), the proton structure (f)unctions F-L and F-2 have been extracted in the region 5 x 10(-4) < x < 0.007 and 20 < Q(2) < 130 GeV2.
