Abstract
We investigate pi and eta decays of light baryon resonances within a chiral quark model whose hyperfine interaction is based on Goldstone-boson exchan ge. For the decay mechanism a modified version of the P-3(0) model is emplo yed. We compare the predictions for pi and eta decay widths with experiment and also with results from a traditional one-gluon-exchange constituent qu ark model. The differences between nonrelativistic and semirelativistic ver sions of the constituent quark models are outlined.
