The spin 1/2 baryons are pictured as a composite system made out of a 'core' of three valence quarks (as in the simple quark model) surrounded by a 'sea' (of gluon and qq-bar pairs) which is specified by its total quantum numbers. We assume the sea is a SU(3) flavor octet with spin 0 or 1 but no color. This model, considered earlier, is used to obtain simultaneous fits for magnetic moments and G{sub A}/G{sub V} for semileptonic decays. These fits give predictions for nucleon spin distributions in reasonable agreement with experiment.
