Abstract
We observe 441 candidate events with a background of 4.2 events and measure in the KTeV/E799II experiment at Fermilab. Using the distribution of the angle between the planes of the pairs, we measure the CP parameters and . We also present the first detailed study of the invariant mass spectrum in this decay mode.
