The production of charmed particles has been measured using a hybrid emulsion spectrometer in the Fermilab wide-band neutrino beam. The relative cross section for charged current charmed particle production is σ( v → μ −c)/ σ( v → μ −) = 6.5 ± 1.9 1.8%, and the energy dependence of the cross section is presented. One event with charm pair production was observed. A limit of σ(v → μ c c)/σ(v → μ c) < 6% (90% CL ) is found for the ratio of charged current pair and single charm production.
