Abstract

We report on the observation of η_c′(2¹S₀), the radial excitation of η_c(1¹S₀), the ground state of charmonium in the two-photon fusion reaction γγ → ηc′ → KS0K±π± in 13.4 fb^-1 of CLEO II/II.V data and 9.2 fb^-1 of CLEO III data. The data have been analyzed to extract the ηc′ resonance parameters. The results from recent observations of ηc′ by Belle and BaBar are also presented.
