Abstract
We present measurements of the lifetimes and polarization amplitudes for and decays. Lifetimes of the heavy and light mass eigenstates in the system are separately measured for the first time by determining the relative contributions of amplitudes with definite as a function of the decay time. Using decays we obtain and . Expressed in terms of the difference and average , of the decay rates of the two eigenstates, the results are and .
