Abstract
The addition of pion contributions to symmetric-quark-model predictions of baryon magnetic moments is shown to lead to considerable improvement in quantitative agreement with experiment. The added variation of the nucleon quark moment in the hyperons, interpreted as a relativistic effect, removes all salient difficulties in reconciling the quark model with accurate magnetic-moment measurements. The pion probability required in the nucleon wave function is found to be (18±7)%.
