A search for a strangeness-2 exotic meson ($X^{+}$) with mass less than two kaon masses has resulted in a limit on the cross section for the production of this particle in the reaction $K^{+}+n\to {\Lambda }^0+X^{+}$. For 1.9-GeV/c incident $K^{+}\text{'}\mathrm{s}$, this cross section is less than 3.3 μb with 90% confidence. The known cross section for the analogous reaction ${\pi }^{+}+n\to {\Lambda }^0+K^{+}$ is about 170 μb at this energy, or more than 50 times larger.
