Abstract
Data from the NA31 experiment at CERN have been used to measure the br anching ratio of the double Dalitz decay of the long-lived neutral kao n. Eight events have been found with negligible background. The measur ed distribution of the angle between the planes of the two e(+)e(-)-pa irs favours a CP = -1 state for the long-lived neutral kaon.
