chi(c0) and chi(c2) decays into eta eta, eta eta ', and eta 'eta ' final states

Using a sample of 3 x 10^6 psi(2S) decays collected by the CLEO III and CLEO_c detector configurations, we present results of a study of \chi_{c0} and \chi_{c2} decays into eta-eta, eta-etaprime, and etaprime-etaprime final states. We find B(chi_{c0} -> eta-eta)= (0.31+-0.05+-0.04+-0.02)%, B(chi_{c0} -> eta-etaprime) etaprime-etaprime) = (0.17 +- 0.04 +-0.02 +-0.01)%. We also present upper limits for the decays of \chi_{c2} into these final states. These results give information on the decay mechanism of \chi_c states into pseudoscalars.
