Inclusive electron scattering is measured with 4.045 GeV incident beam ener
gy from C, Fe, and Au targets. The measured energy transfers and angles cor
respond 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 init
ial nucleon momenta significantly greater than the nuclear matter Fermi mom
entum (i.e., >0.3 GeV/c).
