Abstract
We present a measurement of the decay amplitudes in channels using of data collected at the resonance with the BABAR detector at PEP-II. We measure a -wave fraction and a longitudinal polarization fraction . The measurement of a relative phase that is neither 0 nor , radians, favors a departure from the factorization hypothesis. Although the decay proceeds mainly via , there is also evidence for and -wave contributions.
