Abstract

We report a search for the decay ψ(2S)→γηc(2S) in a sample of 25.9×106 ψ(2S) events collected with the CLEO-c detector. No signals are observed in any of the 11 exclusive ηc(2S) decay modes studied, or in their sum. Product branching fraction upper limits are determined as a function of Γ[ηc(2S)] for the 11 individual modes.
