A high-statistics experiment on ..pi../sup -/p..-->..K/sup -/K/sup +/n and ..pi../sup +/n..-->..K/sup -/K/sup +/p at 6 GeV/c confirms the K-barK S-wave enhancement near 1300 MeV recently observed by Cason et al. in ..pi../sup -/p..-->..K/sub S//sup 0/K/sub S//sup 0/n. Using the P-wave amplitude and the isospin dependence of interfering K-barK states, partial-wave ambiguities are resolved and the S wave is found to be dominantly isospin I=0, with a slow variation of phase. This excludes the interpretation of Cason et al. that the S wave enhancement is a narrow I=1 state. (AIP)
