Ratios of cross sections of carbon, calcium and lead at low x(sub Bj) in inelastic muon scattering

摘要

Shadowing is observed in the per nucleon cross sections of carbon, calcium and lead, as compared to deuterium. Preliminary cross section ratios are presented in the kinematic region x(sub Bj) > 0.0001 and Q(sup 2) (ge) 0.1. The data were taken by Fermilab experiment E665 using inelastically scattered events from muons of mean incident momentum 468 GeV/c.
