Abstract We have observed exclusive decays of the {psi}{sup {prime}} in an experiment where the {psi}{sup {prime}} is formed in antiproton-proton annihilations. We report the branching ratios {ital B}({psi}{sup {prime}}{r_arrow}e{sup +}e{sup {minus}})=(8.3{plus_minus}0.5{sub stat}{plus_minus}0.7{sub syst}){times}10{sup {minus}3}, {ital B}({psi}{sup {prime}}{r_arrow}J/{psi}{pi}{sup +}{pi}{sup {minus}})=0.283{plus_minus}0.021{sub stat}{plus_minus}0.020{sub syst}, {ital B}({psi}{sup {prime}}{r_arrow}J/{psi}{pi}{sup 0}{pi}{sup 0})=0.184{plus_minus}0.019{sub stat}{plus_minus}0.013{sub syst}, {ital B}({psi}{sup {prime}}{r_arrow}J/{psi}{eta})=0.032{plus_minus}0.010{sub stat}{plus_minus}0.002{sub syst}. {copyright} {ital 1997} {ital The American Physical Society}
