Total cross sections for νsub(μ) and anti νsub(μ) charged-current interactions between 20 and 200 GeV

Exposures of the NeH2 filled Big European Bubble Chamber (BEBC) to a dichromatic neutrino (antineutrino) beam produced by 400 GeV protons of the CERN SPS yielded approx. equal to 3100 events with a negative, and approx. equal to 1100 with a positive, muon. The neutrino flux is determined from the muon flux in the shielding. Assuming a linear energy dependence of the cross section, the values sigma/E between 20 and 200 GeV are found to be 0.657 +- 0.012 (stat.) +- 0.027 (syst.) and 0.309 +- 0.009 (stat.) +- 0.013 (syst.) cm2 (GeV nucleon)-1, for neutrinos and antineutrinos, respectively. The scaling variable q2/E decreases significantly with increasing energy both for neutrinos and antineutrinos. (orig.)
