Abstract

We report measurements of the decays ${D}^{+}\ensuremath{\rightarrow}{\overline{K}}^{0}{\ensuremath{\pi}}^{+}$, ${D}^{+}\ensuremath{\rightarrow}{\overline{K}}^{0}{K}^{+}$, and $D_{s}^{}{}_{}{}^{+}\ensuremath{\rightarrow}{\overline{K}}^{0}{K}^{+}$ from Fermilab photoproduction experiment E691. The relative branching fractions obtained are $\frac{B({D}^{+}\ensuremath{\rightarrow}{\overline{K}}^{0}{\ensuremath{\pi}}^{+})}{B({D}^{+}\ensuremath{\rightarrow}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{+})}=0.274\ifmmode\pm\else\textpm\fi{}0.030\ifmmode\pm\else\textpm\fi{}0.031$, $\frac{B({D}^{+}\ensuremath{\rightarrow}{\overline{K}}^{0}{K}^{+})}{B({D}^{+}\ensuremath{\rightarrow}{\overline{K}}^{0}{\ensuremath{\pi}}^{+})}=0.271\ifmmode\pm\else\textpm\fi{}0.065\ifmmode\pm\else\textpm\fi{}0.039$, and $\frac{B(D_{s}^{}{}_{}{}^{+}\ensuremath{\rightarrow}{\overline{K}}^{0}{K}^{+})}{B(D_{s}^{}{}_{}{}^{+}\ensuremath{\rightarrow}\ensuremath{\varphi}{\ensuremath{\pi}}^{+})}=1.15\ifmmode\pm\else\textpm\fi{}0.31\ifmmode\pm\else\textpm\fi{}0.19$.
