Abstract: Cryogenically sensitive nuclear emulsion was placed inside the 15-foot bubble chamber of FNAL and exposed to a wide-band energy (up to 200 GeV) neutrino beam. 194 charged-current neutrino interactions and 13 decays of charmed particles were registered. Using the nuclear emulsion as a vertex detector with the good spectrometric properties of the 15-foot bubble chamber has allowed the decays of charmed particles to be effectively analysed. Attentions is focussed on the new physical results. ?<subscript>c</subscript><superscript>+</superscript> baryon andD<subscript>s</subscript><superscript>+</superscript> meson decay channels, production of charmed ?<subscript>c</subscript> baryons and ?<subscript>c</subscript><superscript>+</superscript> via ?<subscript>c</subscript>.
