Abstract:	The total ν_μ and $ν_{μ}$ nucleon charged-current cross sections have been measured in BEBC filled with deuterium and exposed to the wide-band neutrino and antineutrino beams at the CERN-SPS. Assuming a linear energy dependence for the cross sections, σ = aE(?_ν, we obtained the coefficients $a_{νN= 0.62 ± 0.05anda_{νN}= 0.33 ± 0.03} (in units of 10^{?38} cm^{2} /GeV)$ , where the quoted error is mainly systematic. The ratio of the cross sections is $σ_{νN} /σ_{νN} = 0.53 ± 0.03$ .We also determined the ratio of the charged-current cross section for neutrino interactions on neutrons and protons R = σ_νn/σ_νp = 2.10 ± 0.08 (statistical) ±0.22 (sysetmatic). The dependence of R on the variables x, y and E_ν is discussed.
