Abstract

We report on results of a search for the decay mode K_L -> pi⁰ gamma e⁺ e^- conducted by the E162 experiment at KEK. We observed no events and set a 90% confidence level upper limit of Br(K_L -> pi⁰ gamma e⁺ e^-)< 7.1x10^-7 for its branching ratio. This is the first published experimental result on this decay mode.
