Description
Gluon exchange in QCD is shown to lead to systematic flavour-and spin-dependent distortion of quark distribution functions. We relate the Δ-nucleon mass difference, the ratio of neutron and proton inelastic structure functions and the deep inelastic polarisation asymmetries. Excellent agreement is found with existing data and predictions are made for the polarised neutron asymmetry at x> or approx.0.2. (orig.)
