Abstract	Results are presented for $F_{2}^{\rm d}/F_{2}^{\rm p}$ and $R^{\rm d} - R^{\rm p}$ from simultaneous measurements of deep inelastic muon scattering on hydrogen and deuterium targets, at 90, 120, 200 and 280 GeV. The difference $R^{\rm d} - R^{\rm p}$, determined in the range $0.002<x<0.4$ at an average $Q^{2}$ of 5 GeV$^{2}$, is compatible with zero. The $x$ and $Q^{2}$ dependence of $F_{2}^{\rm d}/F_{2}^{\rm p}$ was measured in the kinematic range $0.001<x<0.8$ and $0.1<Q^{2}<145$ GeV$^{2}$ with small statistical and systematic errors. For $x>0.1$ the ratio decreases with $Q^{2}$.

$noimg: Kinematic cuts applied to the eleven data sets classified by energy and trigger. The scattered muon momentum is indicated by $p'$.: Values of $\Delta R=R^{\rm d}-R^{\rm p}$ determined at $x$ and $\langle Q^2 \rangle$. The calculation of $\langle Q^2 \rangle$ takes into account the sensitivity of the data points to $\Delta R$. In addition the $y$ and $\varepsilon$ range of the data for each $x$ bin are given.: The ratio $F_{2}^{\rm d}/F_{2}^{\rm p}$ and the logarithmic slopes $b_2=\mbox{d}(F_{2}^{\rm d}/F_{2}^{\rm p})/\mbox{d}\ln Q^2$ determined at $x$ and $\langle Q^2 \rangle$.$

$Comparison of $F_{2}^{\rm d}/F_{2}^{\rm p}$ (dashed line) and $\sigma_{\rm d}/\sigma_{\rm p}$ (solid lines) for different incident muon energies of 90, 120, 200 and 280~GeV assuming $\Delta R=0.05$. The ratios are shown as a function of $Q^2$ at $x=0.025$ for the $Q^2$ range covered by the data at each incident energy.$ Show more plots
