Abstract

We report measurements of the decays

D^{+} \to {\bar{K}}^{0} π^{+}

,

D^{+} \to {\bar{K}}^{0} K^{+}

, and

D_{s}^{+} \to {\bar{K}}^{0} K^{+}

from Fermilab photoproduction experiment E691. The relative branching fractions obtained are

\frac{B (D^{+} \to {\bar{K}}^{0} π^{+})}{B (D^{+} \to K^{-} π^{+} π^{+})} = 0.274 \pm 0.030 \pm 0.031

,

\frac{B (D^{+} \to {\bar{K}}^{0} K^{+})}{B (D^{+} \to {\bar{K}}^{0} π^{+})} = 0.271 \pm 0.065 \pm 0.039

, and

\frac{B (D_{s}^{+} \to {\bar{K}}^{0} K^{+})}{B (D_{s}^{+} \to φ π^{+})} = 1.15 \pm 0.31 \pm 0.19
