Results are presented of a recent search by AGS Experiment 845 for the CP violating decay K{sub L}{sup 0} {yields} {pi}{sup 0}e{sup +}e{sup {minus}}. The 90% C.L. limit B(K{sub L}{sup 0} {yields} {pi}{sup 0}e{sup +}e{sup {minus}}) < 5.5 {times} 10{sup {minus}9} was obtained. The background to the {pi}{sup 0}e{sup +}e{sup {minus}} search, K{sub L}{sup 0} {yields} e{sup +}e{sup {minus}}{gamma} with an internal bremsstrahlung is discussed. 5 refs., 1 fig.
