Neutral-current differential cross sections as a function of the scaling variable x for deep inelastic neutrino-nucleon and antineutrino-nucleon scattering on an isoscalar target were measured in the CERN SPS 200 GeV/c Narrow-Band Beam with the CHARM fine-grained calorimeter. The data have been corrected for the experimental resolutions using a novel unfolding procedure. Its validity is tested on charged-current reactions. The x-distributions determined in neutral-current reactions are found to be compatible with the results obtained in charged-current reactions, as expected by the quark model of the nucleon and by the standard model of the weak interactions.
