Abstract
| Exposures of the Ne/H/sub 2/ filled Big European Bubble Chamber (BEBC) to a dichromatic neutrino (antineutrino) beam produced by 400 GeV protons of the CERN SPS yielded approximately 3100 events with a negative, and approximately 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+or-0.012 (stat.)+or-0.027 (syst.) and 0.309+or-0.009 (stat.)+or-0.013 (syst.) cm/sup 2/ (GeV nucleon)/sup -1/, for neutrinos and antineutrinos, respectively. The scaling variable q/sup 2//E decreases significantly with increasing energy both for neutrinos and antineutrinos. |
