Abstract

Using the ~ 6 pb-1 of e+e- annihilation data taken at psi-prime(3686) with CLEO III and CLEO-c detectors with estimated ~ 3.0 million psi-prime events, we have searched for the h_c(1¹P₁) state of charmonium in the reaction psi-prime(3686) -> pi⁰ hc -> (gamma gamma) (gamma eta_c). The preliminary results are reported.
