A measurement of J//psi/ ..-->.. ..gamma pi../sup +/..pi../sup /minus//..pi../sup +/..pi../sup /minus// is presented. The f/sub 1/(1285) is observed and its spin and parity are investigated. The /eta//sub c/ is observed to decay to /rho//sup 0//rho//sup 0/, and that first observation of /eta//sub c/ decays to f/sub 2/(1270)f/sub 2/(1270) is presented. 1 ref., 3 figs.
