Shadowing in inelastic scattering of muons on carbon, calcium and lead at low x_B_j

Nuclear shadowing is observed in the per-nucleon cross-sections of positive muons on carbon, calcium and lead as compared to deuterium. The data were taken by Fermilab experiment E 665 using inelastically scattered muons of mean incident momentum 470 GeV/c. Cross-section ratios are presented in the kinematic region 0.0001 < x_B_j < 0.56 and 0.1 < Q"2 < 80 GeV"2. The data are consistent with no significant #nu# or Q"2 dependence at fixed x_B_j. As x_B_j decreases, the size of the shadowing effect, as well as its A dependence, are found to approach the corresponding measurements in photoproduction.
