摘要：

Data from the NA31 experiment at CERN have been used to measure the branching ratio of the double Dalitz decay of the long-lived neutral kaon. Eight events have been found with negligible background. The measured distribution of the angle between the planes of the two e(+)e(-)-pairs favours a CP = -1 state for the long-lived neutral kaon.
