Abstract

The total νμ and νμ 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 aνN = 0.62 ± 0.05 and aνN = 0.33 ± 0.03 (in units of 10-38 cm2/GeV), where the quoted error is mainly systematic. The ratio of the cross sections is σνNνN = 0.53 ± 0.03. We also determined the ratio of the charged-current cross section for neutrino interactions on neutrons and protons R = σνnνp = 2.10 ± 0.08 (statistical) ±0.22 (sysetmatic). The dependence of R on the variables x, y and Eν is discussed.
