We investigate the degree to which the scaling functions F(ψ′) derived
from cross sections for inclusive electron-nucleus quasi-elastic scattering
define the same function for different nuclei. In the region where the scaling
variable ψ′<0, we find that this superscaling is experimentally realized
to a high degree.Comment: Corrected previously mislabeled figures and cross references; 9
