Ratio of Electron Scattering from Nuclei to Deuterium at low x and low Momentum Transfer

Abstract

We have extracted ratios of cross sections for scattering electrons from high mass targets compared to low mass targets in the region of x ~ 0.02 and Q^2 < 1 (GeV/c)^2 from SLAC experiments performed over the past three decades. Additional analysis was needed for radiative corrections, target end caps and calibration runs. We observe no significant difference in the nuclear ratio for low Q^2 compared to results at Q^2 > 1.
