Recent results from neutrino interactions in heavy neon

; ;
We report recent results from an analysis of 100,000 pictures from the Fermilab 15 ft. bubble chamber filled with heavy neon and exposed to the double horn focused, wideband ..nu../sub ..mu../ beam. We have found 164 dilepton (..mu../sup -/e/sup +/) events with 33 vees, in good agreement with the GIM model of charm production. We have also observed the production of the charmed D/sup 0/ meson, followed by the decay D/sup 0/ ..-->.. K/sup 0/..pi../sup +/..pi../sup -/, at a rate of (0.7 +- 0.2)% of all charged current events. We have carried out searches for charm changing neutral current processes and for heavy lepton production, both with negative results; the upper limits obtained in these searches are given.
