Abstract A search for νμ → ν e and $$\bar \nu _\mu \to \bar \nu _e $$ oscillations has been carried out with the CHARM II detector exposed to the CERN wide band neutrino beam. The data were collected over five years, alternating beams mainly composed of muon-neutrinos and muon-antineutrinos. The number of interactions of ν e and $$\bar \nu _e $$ observed is comparable with the number of events expected from flux calculations. For large squared mass differences the upper limits obtained on the mixing angle aresin 22θ 〈 9.4 · 10−3 for νμ oscillating to ν e andsin 22θ 〈 4.8 · 10−3 for $$\bar \nu _\mu $$ to $$\bar \nu _e $$ , at the 90% confidence level. Combining neutrino and antineutrino data the upper limit is 5.6 · 10−3.
