Using the Standard Linear Acelerator Center Hybrid Facility 1-m bubble chamber with tantalum plates, a search was made for single electrons or positrons produced directly in 18-GeV/c ..pi../sup + -/interactions. At 90% confidence level (C.L.), R = e/sup + -//..pi../sup + -/ < 2.4 x 10/sup -5/. In addition, a limit can be set on charmed particle pair or associated production channels in terms of their semielectronic decay branching ratios, namely, sigma(R/sub 1/ + R/sub 2/) < 2.4 ..mu..b at 90% C.L.
