Resumen
We report on a new measurement of the branching ratio B(K-L ->pi(0)e(+)e(-)gamma) 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(K-L ->pi(0)e(+)e(-)gamma)=(1.62 +/- 0.14(stat)+/- 0.09(syst))x10(-8). This result supersedes the earlier KTeV measurement of this branching ratio. 76 5
