A dedicated search for the decays K/sub L//sup 0/ /yields/ /mu/e, K/sub L//sup 0/ /yields/ ee and K/sub L//sup 0/ /yields/ /mu//mu/, was carried out at the Brookhaven National Laboratory AGS (E780). The data obtained were also used in a search for the three-body decays K/sub L//sup 0/ /yields/ /pi//sup 0/l /sup /plus/1/sup /minus//. The two body modes were normalized to the kinelatically similar, CP violating, decay K/sub L//sup 0/ /yields/ /pi//sup (plus///pi//sup /minus//; whereas the three body modes were normalized to the decay K/sub L//sup 0/ /yields/ /pi//sup 0//pi//sup /plus//pi//sup /minus//. The search was performed on a sample of K/sup 0/ mesons produced in the forward direction by the interactions of 29 GeV protons on a copper target, and decaying in a 3 meter long region, starting augmented by a hydrogen Cerenkov counter and a lead glass electromagnetic calorimeter, for electron identification, and by a range stack, for muon identification. 9 refs., 5 figs., 2 tabs.
