Abstract
We report the observation of near with significance in the final state in a data sample of collected by the BABAR experiment at the PEP-II storage rings. We measure the restricted radiation-corrected cross section to be within the range , where is the center-of-mass polar angle of the meson. The meson is required to be in the invariant mass range of . The radiation-corrected cross section in the full range is extrapolated to be .
