Comparison of cross sections from deep-inelastic neutrino scattering on neon and deuterium.

We compare cross sections derived from deep inelastic neutrino scattering on neon and deuterium targets. Systematic effects are minimized by imposing identical analysis criteria on two experiments in the same detector with similiar incident neutrino spectra, and by using variables independent of the beam energy estimate. Our results favor a previously observed dependence of nucleon structure functions on the target nucleus (the EHC effect), but do not require the existence of this phenomenon.
