Abstract

SMC performed an investigation of the spin structure of the nucleon by measuring deep inelastic scattering of polarised mouns off polarised protons and deuterons: Asymmetries and spin structure functions were obtained for x>0.0008 and Q 2>0.2 GeV2. Using a next-to-leading order QCD analysis of all experimental results polarised parton distributions and their first moments were determined. All data show a clear violation of the Ellis-Jaffe sum rule. The Bjorken sum rule is found to be valid and is tested to the 10% level.
