The branching fraction for the decay was measured and a 90% confidence level upper limit was set for the decay. Data was collected at the Y(4S) resonance by the Belle detector at the KEKB asymmetric-energy e+e- collider. Candidate π0 mesons were identified as pairs of non-charged-track-associated electromagnetic calorimeter clusters.text::journal::journal article::research article
