SEARCH FOR THE RARE DECAYS K(L)(0)-]MU-E AND K(L)(0)-]EE

A search for the rare decays K(L)0 --> mu-e and K(L)0 --> ee was performed at the KEK 12-GeV Proton Synchrotron. No event was observed in the fiducial region for the decay K(L)0 --> mu-e. There was one event in the fiducial region for the decay K(L)0 --> ee, which was indistinguishable from the background. The upper limits on the branching ratios at 90% confidence level were B(K(L)0 --> mu-e) < 9.4 x 10(-11) and B(K(L)0 --> ee) < 1.6 x 10(-10).
