The inclusive process ${\pi }^{+}$+P→K¯ ${}_{}{}^{\mathrm{*}0}{}_{}{}^{}$(890)+X is studied at 16 GeV/c using a 2-m streamer chamber containing a central liquid hydrogen target. From photographs triggered by detection of a forward $K^{\mathrm{-}}$ meson, the signal K¯ ${}_{}{}^{\mathrm{*}0}{}_{}{}^{}K_{}^{\mathrm{-}}{}_{}{}^{}$${\pi }^{+}$ is extracted. The inclusive rate for K¯ ${}_{}{}^{\mathrm{*}}{}_{}{}^{}$ production into the forward hemisphere σ($x_F$>0.3) is 115±27 μb; the $p_T$${}^2$ distribution is found to have a slope constant of 3.3±0.6 (GeV/c${)}^2$. The Feynman-x distribution for K¯ ${}_{}{}^{\mathrm{*}0}{}_{}{}^{}$ is consistent with a Kuti-Weisskopf model in which the valence and sea quarks of the incident pion interact with only the sea quarks of the target proton.
