摘要：Baryon magnetic moments and beta decay ratios (GA=GV ) are calculated in
a phenomenological quark model. Non-static e
ects of pion exchange and some orbital
excitation are included. Good agreement with experiment is found for a combined t to
all measured baryon magnetic moments and beta decay ratios. The model predicts an
antiquark content for the proton that is consistent with the Gottfried sum rule.
