摘要
We report a search for the decay psi(2S) -> gamma eta(c)(2S) in a sample of 25.9 x 10(6) psi(2S) events collected with the CLEO-c detector. No signals are observed in any of the 11 exclusive eta(c)(2S) decay modes studied, or in their sum. Product branching fraction upper limits are determined as a function of Gamma[eta(c)(2S)] for the 11 individual modes.
