摘要：

Two events with the characteristics of the decay K(L)0 --> e+ e- e+ e- have been observed with a negligible expected background from which a branching ratio of (4 +/- 3) x 10(-8) is derived. This result is consistent with values estimated from theoretical models based on the double internal conventional of the decay K(L)0 --> gamma-gamma.
