Inclusive K/sup 0//K-bar/sup 0/, ..lambda../sup 0/, and Lambda-bar/sup 0/ cross sections have been determined using a 292-event/mb exposure of the hydrogen-filled 15-foot bubble chamber at Fermilab. From the invariant-mass distributions of V/sup 0/..pi../sup + -/ pairs we find that sigma(K*/sup + -/(890))=4.4 +- 1.4 mb, sigma(..sigma..*/sup + -/(1385))=0.54 +- 0.40 mb, and sigma(Sigma-bar*/sup + -/(1385))=0.45 +- 0.34 mb. It is estimated that 0.32 +- 0.11 of K/sup 0//K-bar/sup 0/'s, 0.21 +- 0.16 of ..lambda..'s, and 0.96 +- 0.75 of Lambda-bar's originate from decays of K*(890) and ..sigma..*(1385), respectively.
