Abstract We present the final results from the search for μe pairs produced in neutrino interactions using the freon filled bubble chamber SKAT. The rate of μ− e + pairs to charged current events above the charm threshold is $$R_{\mu ^ - e^ + } = (4.8 \pm 1.1)10^{ - 3} $$ . Assuming charm particle production to be the origin of the positron we calculate $$R_{\Lambda _c^ + } = (6.2 \pm 3.1)10^{ - 2} $$ andR D =(2.8±0.9)10−2. We observe no considerable μ− e − pair production above the background. In the regionE v 〉3 GeV,p μ,e 〉1.0 GeV/c andp μ〉p e we find with a 90% confidence level the limit $$R_{\mu ^ - e^ - }〈 1.7 10^{ - 4} $$ .
