Abstract
We present a series of measurements based on and decays collected in 1996–1997 by the experiment (E832) at Fermilab. We compare these four decay rates to measure the direct violation parameter We also test symmetry by measuring the relative phase between the violating and conserving decay amplitudes for and for We find the difference between the relative phases to be and the deviation of from the superweak phase to be both results are consistent with symmetry. In addition, we present new measurements of the - mass difference and lifetime: and
