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 GeV(2).

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 GeV(2).
