Phys. Rev. D 62, 032004 (2000) [8 pages]Measurement of the branching ratios ψ′→e+e-, ψ′→J/ψπ0π0 and ψ′→J/ψηReceived 18 February 2000; published 11 July 2000 We have determined the following ψ′ branching ratios using the large event sample collected by Fermilab experiment E835 in the reaction pp̅ →ψ′: B(ψ′→e+e-)=(7.4±0.2±0.7)×10-3, B(ψ′→J/ψπ0π0)=(18.7±0.9±1.3)% and B(ψ′→J/ψη)=(4.1±0.3±0.5)%. © 2000 The American Physical Society URL:
