We present a study of D/sup 0/ mixing using events of the type D/sup *//sup +/..--> pi../sup +/D/sup 0/, with D/sup 0/..-->..K/sup +/..pi../sup -/ and D/sup 0/..-->..K/sup +/..pi../sup -/..pi../sup +/..pi../sup -/. The decay time is used to separate mixing from doubly Cabibbo-suppressed decays. We observe no evidence for mixing in either mode. Combining the results from the two decay modes, we find r/sub M/ = 0.0005 +- 0.0020 or r/sub M/<0.0037 at the 90% confidence level, where r/sub M/ is the ratio of wrong-sign decays from mixing to right-sign decays. We also present limits on doubly Cabibbo-suppressed decays and consider the effect of possible interference.
