Abstract

We present a measurement of the photon structure function F₂^γ in the reaction ee→eeX for Q² in the range 0.2<Q²<7 GeV², using 9,200 multihadron events obtained with the TPC/Two-Gamma detector at PEP. The data have been corrected for detector effects using a regularized unfolding procedure and are presented as a function of x and Q². The structure function shows scaling in the region 0.3<Q²<1.6 GeV², x<0.3 and rises for higher Q². At Q²=5.1 GeV² the results are compared with QCD and, within the scheme of Antoniadis and Grunberg, rather conservative bounds for the QCD scale parameter of 133±50< {Mathematical expression}<268±98 MeV are obtained. A study of the final state structure shows that the rise of F₂^γ is consistent with being entirely due to the pointlike component of the photon.
