A search has been performed for the muon-number-violating decay ..mu.. ..-->.. e/sup +/e/sup +/e/sup -/. No candidate event has been found, yielding an upper limit for the branching ratio of B/sub ..mu..3e/ < 1.3 x 10/sup -10/ (90% C.L.). From part of the data taken with a trigger that enhanced ..mu../sup +/ ..-->.. e/sup +/e/sup +/e/sup -/ anti nu/sub ..mu../nu/sub e/ events, 11 such events were observed. They agree in number and spectra with expectations based on standard electroweak theory. 9 references.
