Upper limits of 1.1 % and 0.4% are found on the yields of cumulative Δ 0 and Δ + + particles, respectively, on the basis of —5100 neutrino interactions with neon nuclei observed with the 15-foot Fermilab bubble chamber at a 90% confidence level. It is concluded that the EMC effect cannot be explained by the isobar model.
