We apply a simple diquark model to the calculation of the decay cross-sections for the reactions J/psi --> (p) over barp, (p) over bar N* (1440), (N) over bar N*, (&ULambda;) over bar Lambda and (&USigma;) over bar (0)Sigma(0). The results are different from those given by the ordinary constituent quark model. Hence these reactions may provide a new check of two different pictures for the baryons.
