Abstract
Preliminary results on the measurement of the cross-section ratio {sigma}{sub n}/{sigma}{sub p} in inelastic {mu}p and {mu}d scattering are presented. The cross-section ratio {sigma}{sub n}/{sigma}{sub p} is presented as a function of x{sub Bj}. This ratio is determined using three different techniques and is measured with high precision for x{sub Bj} > 10{sup {minus}6}. This extends the knowledge of {sigma}{sub n}/{sigma}{sub p} to much lower x{sub Bj} with smaller statistical uncertainties than previous results. First measurements of F{sup p}{sub 2}(x,Q{sup 2}) and F{sup d}{sub 2}(x,Q{sup 2}) from experiment E665 are also presented in the range x{sub Bj} > 8 {times} 10{sup {minus}4} and Q{sup 2} > 0.2 GeV{sup 2}/c{sup 2}. This extends the kinematic range in which F{sub 2} is measured.
