Scientific paper

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 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 GA/GV for semileptonic decays. These fits give predictions for nucleon spin distributions in reasonable agreement with experiment.
