Cross sections for {pi}- and {rho}-induced dissociation of J/{psi} and {psi}{prime}

We evaluate the cross sections for the dissociation of J/{psi} and {psi}{prime} by {pi} and {rho} at low collision energies, using the quark-interchange model of Barnes and Swanson. The dissociation cross section for J/{psi} by {pi} is found to be relatively small with a maximum of about 1 mb and a kinetic energy threshold of 0.65 GeV. The pion-induced {psi}{prime} dissociation cross section is found to be much larger, with a maximum of about 5 mb and a lower threshold. Dissociation cross sections for J/{psi} and {psi}{prime} by {rho} mesons are also evaluated and are found to be large near threshold.
