The /ital K//sub /ital S///sup 0/K/sub S//sup 0//pi//sup 0/ systems, a pure /ital C/=+1 state, has been studied in the reaction /pi//sup /minus//p/r arrow/K/sub S//sup 0/K/sub S//sup 0//pi//sup 0/n at 21.4GeV//ital c/. The /ital K//sub /ital S///sup 0/K/sub S//sup 0//pi//sup 0/ spectrum is significantly different from the /bar /ital KK///pi/ distribution observed in other lower-energy peripheral hadroproduction experiments. In addition to production of the /ital f//sub 1/(1285), evidence for production of the /eta/(1460) (sometimes called the /iota/(1460)) based on mass spectra and a Dalitz-plot spin-parity analysis is reported. The narrower, lower-mass state observed in other /bar /ital KK///pi/ experiments is observed weakly if at all in this experiment. Hadronic production of the /eta/(1460), which is a good glueball candidate because of its presence in /ital J///psi/ radiative decay, suggests possible mixing with the /bar /ital qq// sector.
