Cross sections for deep-inelastic electron scattering from liquid deuterium, gaseous [sup 4]He, and solid Be, C, Al, Ca, Fe, Ag, and Au targets were measured at the Stanford Linear Accelerator Center using electrons with energies ranging from 8 to 24.5 GeV. These data cover a range in the Bjorken variable [ital x] from 0.089 to 0.8, and in momentum transfer [ital Q][sup 2] from 2 to 15 (GeV/[ital c])[sup 2]. The ratios of cross sections per nucleon ([sigma][sup [ital A]]/[sigma][sup [ital d]])[sub is] for isoscalar nuclei have been extracted from the data. These ratios are greater than unity in the range 0.1[lt][ital x][lt]0.3, while for 0.3[lt][ital x][lt]0.8 they are less than unity and decrease logarithmically with atomic weight [ital A], or linearly with average nuclear density. No [ital Q][sup 2] dependence in the ratios was observed over the kinematic range of the data. These results are compared to various theoretical predictions.
