Fermilab experiment 665 has taken deep-inelastic muon scattering data at a beam energy of 490 GeV/c, on H{sub 2}, D{sub 2} and Xe targets. Two triggers have been used: a large scattering-angle trigger (LAT), sensitive to a minimum scattering angle of 3 mrad, and a small scattering-angle trigger which can accept a scattering angle down to 0.5 mrad. The neutron to proton ratio is reported for x{sub bj} above 0.002, and it shows consistency with 1 as x{sub bj} goes to 0. The Xe to D{sub 3} cross-section ratio is reported for x{sub bj} above 0.001 and it shows evidence of shadowing. 5 refs., 5 figs.
