Abstract

The photon structure function F2 has been measured at average Q2 values of 73,160 and 390 (GeVc)2. We compare the x dependence of the Q2 = 73 (GeVc)2 data with theoretical expectations based on QCD. In addition we present results on the Q2 evolution of the structure function for the intermediate x range (0.3⩽ x ⩽0.8). The results are consistent with QCD.
