Abstract

We have measured the process e⁺e^-→e⁺e^-+hadrons, where one of the scattered electrons was detected at large angles, with Q² ranging from 7 to 70 (VeV/c)². The photon structure function F₂ ^γ(x, Q²) was determined at an average Q² of 23 (GeV/c)². The measurements were compared to theoretical predictions of the Quark Parton Model and Quantum Chromodynamics. In both models a hadronic part was added. Within the errors the data are in agreement with the QPM using quark masses of 300 MeV/c² for the light quarks. The data also agree with a QCD calculation including higher order corrections. A fit yielded a {Mathematical expression} value of 140_-65 ⁺¹⁹⁰ MeV, where the errors include statistical and systematic uncertainties.
