Abstract
We report on results of a search for the decay mode K-L --> pi(0)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 --> pi(0)gamma e(+)e(-)) < 7. 1 x 10(-7) for its branching ratio. This is the first published experimenta l result on this decay mode. (C) 1999 Elsevier Science B.V. All rights rese rved.
