Inclusive Electron-Nucleus Scattering at Large Momentum Transfer

Abstract

Inclusive electron scattering is measured with 4.045 GeV incident beam energy from C, Fe and Au targets. The measured energy transfers and angles correspond to a kinematic range for Bjorken $x>1$ and momentum transfers from $Q^2=1-7(GeV/c{)}^2$. When analyzed in terms of the y-scaling function the data show for the first time an approach to scaling for values of the initial nucleon momenta significantly greater than the nuclear matter Fermi-momentum (i.e. $>0.3$ GeV/c).
