Abstract:We have developed a method to separate νn and νp interactions from antineutrino-neon interactions by using the final state electric charge. We present the distributions of the scaling variables x and y for νn and νp interactions separately , along with the νn and νp cross section ratios as a function of x and y. We obtain a total νn to νp cross section ratio of 0.45± 0.08. Our results are consistent with the predictions of the simple quark parton model.
