Measurement of the photon structure function F2γ at low x

Deep inelastic electron-photon scattering is studied using e⁺e^- data collected by the OPAL detector at centre-of-mass energies sqrt(s_ee)~M_Z⁰. The photon structure function F₂^γ(x,Q²) is explored in a Q² range of 1.1 to 6.6 GeV² at lower x values than ever before. To probe this kinematic region events are selected with a beam electron scattered into one of the OPAL luminosity calorimeters at scattering angles between 27 and 55 mrad. A measurement is presented of the photon structure function F₂^γ(x,Q²) at <Q²>=1.86 GeV² and 3.76 GeV² in five logarithmic x bins from 0.0025 to 0.2.
