We present a measurement of the time-dependent asymmetry in the rate for versus decays to . A nonzero asymmetry would be an indication of violation, and within the standard model this may be used to measure the -violation parameter . A total of decays were observed in collisions at by the CDF detector at the Fermilab Tevatron. and are distinguished by a technique based on charge correlations from hadronization of the quark. Our analysis results in .
