Add to ORKGThe decay rate of the long-lived neutral K meson into the e+ e− e+ e− final state has been measured with the NA48 detector at the CERN SPS. Using data collected in 1998 and 1999, a total of 200 events has been observed with negligible background. This observation corresponds to a branching ratio of Br(KL → e+ e− e+ e− ) = (3.30 ± 0.24(stat) ± 0.23(syst) ± 0.10(norm) ) × 10^−8
