Abstract:	We report on a new measurement of the branching ratio B(KL→π0e+e- γ) using the KTeV detector. This analysis uses the full KTeV data set collected from 1997 to 2000. We reconstruct 139 events over a background of 14, which results in B(KL→π0e+e-γ)=(1.62±0.14stat±0. 09syst)×10-8. This result supersedes the earlier KTeV measurement of this branching ratio. © 2007 The American Physical Society.
