Abstract We report on results of a search for the decay mode K L → π 0 γe + e − conducted by the E162 experiment at KEK. We observed no events and set a 90% confidence level upper limit of Br ( K L → π 0 γe + e − ) −7 for its branching ratio. This is the first published experimental result on this decay mode.
