Experiment WA82 studied charm production by a π − beam of 340 GeV/ c at the CERN Ω′ spectrometer, using a silicon microstrip vertex detector and an impact parameter trigger. Results on the x F distributions of D + and D − mesons are presented and discussed. A clear excess of D − over D + , increasing at high x F , is observed.
