MAGNETIC-MOMENTS OF THE 3 2 RESONANCES AND THEIR QUARK SPIN STRUCTURE/

We discuss magnetic moments of the J = 3/2 baryons based on an earlier model for the baryon magnetic moments, allowing for flavor symmetry b reaking in the quark magnetic moments as well as a general quark spin structure. From our earlier analysis of the nucleon-hyperon magnetic m oments and the measured values of the magnetic moments of Delta(++) an d Omega(-) we predict the other magnetic moments and deduce the spin s tructure of the resonance particles. We find from experiment that the total spin polarization of the decuplet baryons, Delta Sigma(3/2), is considerably smaller than the nonrelativistic quark model value of 3, although the data are still not good enough to give a precise determin ation.
