Nucleon Structure Functions from High Energy nu - Interactions at the Fermilab Tevatron.

Nucleon structure functions has been extracted from high energy neutrino-nucleon interactions data taken with the CCFR detector. The experiments were performed in Fermi National Accelerator Laboratory. The data sample consisted of 1,050,000 neutrino and 180,000 antineutrino induced events with neutrino energies ranging from 30 to 600 GeV. The physics results include a most precise measurement of the Gross-Llewellyn Smith Sum Rule, S_ {GLS}=2.50+/- 0.02+/- 0.08. Tests were made to perturbative Quantum Chromodynamics, including a measurement of Lambda_{overline {MS}} obtained from fitting to non -singlet structure function, Lambda_ {overline{MS}}=215+/- 23 +/- 34 MeV. A measurement of the ratio of neutrino to antineutrino cross section of charged-current interactions was also obtained, yielding sigma ^{|nu}/sigma ^nu=.518+/- .002+/- .006..
