Abstract
A measurement of the proton spin structure function g(l)(p)(x, Q(2)) in dee p-inelastic scattering is presented. The data were taken with the 27.6 GeV longitudinally polarised positron beam at HERA incident on a longitudinally polarised pure hydrogen gas target internal to the storage ring. The kinem atic range is 0.021 < x < 0.85 and 0.8 GeV2 < Q(2) < 20 GeV2. The integral integral(0.021)(0.85) g(l)(p)(x) dx evaluated at Q(0)(2) of 2.5 GeV2 is 0.1 22 +/- 0.003(stat.) +/- 0.010(syst.).
