Abstract

We have observed 99 decays of the charmed strange meson, the

D_{s}^{+}

(formerly called the

F^{+}

), into the φ

π^{+}

(61) and K

¯^{* 0}

K^{+}

(38) final states in the Fermilab photoproduction experiment E-691. We determine the lifetime to be (0.

48_{- 0.05}^{+ 0.06}

±0.02)×

10^{- 12}

s. Using our reported measurement of the

D^{0}

lifetime, we calculate the ratio τ(

D_{s}^{+}

)/τ(

D^{0}

)=(1.10±0.15±0.04).
