Phys. Rev. Lett. 60, 1471–1474 (1988)Spin content of the protonReceived 11 January 1988; published in the issue dated 11 April 1988 Data on polarized lepton-proton scattering are shown to give no clear conclusion on the spin content of the proton. We argue that errors have been underestimated, specifically those arising from the uncertainty of the extrapolation to infinite energy (x→0). Estimates of the spin content are sensitive to such uncertainty and possible ways of surmounting this problem are discussed. © 1988 The American Physical Society URL:
