Abstract
We have observed exclusive decays of the psi' in an experiment where t he psi' is formed in antiproton-proton annihilations. We report the br anching ratios B(psi' --> e(+)e(-)) = (8.3 +/- 0.5(stat) +/- 0.7(syst) ) x 10(-3), B(psi' --> J/psi pi(+)pi(-)) = 0.283 +/- 0.021(stat) +/- 0 .020(syst), B(psi' --> J/psi pi(0) pi(0)) = 0.184 +/- 0.019(stat) +/- 0.013(syst), B(pi' --> J/psi eta) = 0.032 +/- 0.010(stat) +/- 0.002(sy st).
