Abstract.

Within a perturbative approach we investigate decays of charmonium states into baryon-antibaryon pairs. Using a recently proposed wave function for the nucleon and suitable generalizations of it to the hyperons and decouplet baryons, we obtain the decay widths for the \(B\overline B\) channels in reasonable agreement with data. An important difference to previous work is the use of the \(c\)-quark mass in the perturbative calculation instead of the charmonium mass. As a consequence of this feature our approach possesses the property that the \(J/\psi\) and the \(\psi'\) decay widths do not scale with a high power of the ratio of their masses.
