Abstract
Using data collected with the CLEO detector operating at the CESR collider at , we investigate 15 charmonium decay modes of the , , and resonances. We confirm, at significance, the BABAR discovery, make the first observation of (), and find the first evidence for (). We measure cross sections at as , , and , in which the uncertainties are statistical and systematic, respectively. Upper limits are placed on other decay rates from all three resonances.
