Abstract
A measurement of the inclusive cross section for the deep-inelastic sc attering of positrons off protons at HERA is presented at momentum tra nsfers 8.5 less than or equal to Q(2) less than or equal to 35 GeV2 an d large inelasticity (y)=0.7, i.e. for the Bjorken-x range 0.00013 <x <0.00055. Using a next-to-leading order QCD fit to the structure funct ion F-2 at lower y values, the contribution of F-2 to the measured cro ss section at high y is calculated and, by subtraction, the longitudin al structure function F-L is determined for the first time with an ave rage value of F-L=0.52+/-0.03 (stat)(-0.22)(+0.25) (syst) at Q(2)=15.4 GeV2 and x=0.000243.
