The author has measured inclusive electron-scattering cross sections for targets of {sup 4}He, C, Al, Fe, and Au, for kinematics spanning the quasi-elastic peak, with squared, four-momentum transfer (q{sup 2}) between 0.23 and 2.89 (GeV/c){sup 2}. Additional data were measured for Fe with q{sup 2}'s up to 3.69 (GeV/c){sup 2}. These cross sections were analyzed for the y-scaling behavior expected from a simple, impulse-approximation model, and are found to approach a scaling limit at the highest q{sup 2}'s. The q{sup 2} approach to scaling is compared with a calculation for infinite nuclear matter, and relationships between the scaling function and nucleon momentum distributions are discussed. Deviations from perfect scaling are used to set limits on possible changes in the size of nucleons inside the nucleus.
