Abstract

We report the observation of the Cabibbo-suppressed decays

Λ_{c}^{+} \to p K^{-} K^{+}

and

Λ_{c}^{+} \to p φ

using data collected with the CLEO II detector at CESR. The latter mode, observed for the first time with significant statistics, is of interest as a test of color suppression in charm decays. We have determined the branching ratios for these modes relative to

Λ_{c}^{+} \to p K^{-} π^{+}

and compared our results with theory.
