We have performed a partial-wave analysis of the K/sup +/K-bar/sup o/..pi../sup -/ system produced in the reaction ..pi../sup -/p..-->..K/sup +/K-bar/sup o/..pi../sup -/n at 8.0 GeV/c. We find that the D(1285) is a J/sup PG/ = 1/sup + +/ state coupling predominantly to a delta..pi.. decay channel, while the E(1420) peak consists mostly of a J/sup PG/ = 0/sup - +/ wave with a substantial delta..pi.. decay mode. There is little evidence of a 1/sup + +/ resonance at the E mass.
