We study the decays of the decuplet of baryon resonances in the framework of the nonlocal quark model. We construct a Lagrangian which describes the strong interaction of spin J/sup P/ = 3/2/sup +/ particles with quarks, and which is invariant under SU (3). All parameters which characterize the quark field have been determined from an analysis of meson decays. Matrix elements of the S matrix are calculated on a computer using analytical programming methods. Strong-decay widths for the decuplet are considered and the magnetic moments of the D--B transition are calculated. The effective expansion parameter in perturbation theory is found to be less than unity. The results are in good agreement with the experimental data.
