Comparison of the F2 Structure Function in Iron as Measured by Charged Lepton and Neutrino Probes

World data for the structure function $F_{2}$ for Iron from charged lepton and neutrino scattering experiments are compared. The observations cleanly underscore previously observed hints of a difference in the behavior of the data between charged lepton and neutrino scattering, notably in the anti-shadowing region where the Bjorken scaling variable $x$ is below 0.15. The charged lepton data appear to undergo shadowing/anti-shadowing whereas the neutrino data seem to exhibit no nuclear effects. Moreover, we find very good agreement between the different types of probes in the $x$ region above 0.15. Details and results of the data comparison are shown in this talk.
