Abstract
We report determination of branching fractions for the decays psi(2S)-> h+J/psi, where h=any, pi(+)pi(-), pi(0)pi(0), eta, pi(0), and gamma gamma through chi(c0,1,2). These measurements use 27M psi(2S) decays produced in e(+)e(-) collision data collected with the CLEO detector. The resulting branching fractions and ratios thereof improve upon previously achieved precision in all cases, and in combination with other measurements permit determination of B(chi(cJ)->gamma J/psi) and B(psi(2S)-> light hadrons).
