Abstract
The photon structure function F-2(gamma) has been measured at average Q(2) values of 73 and 390 GeV2 using data collected by the AMY detecto r at the TRISTAN e(+)e(-) collider. F-2(gamma) is observed to be incre asing as In Q(2). The x-dependence of F-2(gamma), where x is the momen tum fraction carried by the parton inside the photon, is also measured . The measurements are compared with several parton density models.
