A re-evaluation of the nuclear structure function ratios for D, He, 6Li, C and Ca

We present a re-evaluation of the structure function ratios F₂^He/ F₂^D, F₂^C/ F₂^D and F₂^Ca/ F₂^D measured in deep inelastic muon-nucleus scattering at an incident muon momentum of 200 GeV. We also present the ratios F₂^C/ F₂^Li, F₂^Ca/ F₂^Li and F₂^Ca/ F₂^C measured at 90 GeV. The results are based on data already published by NMC; the main difference in the analysis is a correction for the masses of the deuterium targets and an improvement in the radiative corrections. The kinematic range covered is 0.0035 < x < 0.65 < Q² < 90 GeV ² for the He/D, C/D and Ca/D data and 0.0085 < x < 0.6, 0.84 < Q² < 17 GeV ² for the Li/C/Ca ones.
