We have determined the following {psi}{sup '} branching ratios using the large event sample collected by Fermilab experiment E835 in the reaction pp(bar sign){yields}{psi}{sup '}: B({psi}{sup '}{yields}e{sup +}e{sup -})=(7.4{+-}0.2{+-}0.7)x10{sup -3}, B({psi}{sup '}{yields}J/{psi}{pi}{sup 0}{pi}{sup 0})=(18.7{+-}0.9{+-}1.3)% and B({psi}{sup '}{yields}J/{psi}{eta})=(4.1{+-}0.3{+-}0.5)%.
