  We use the variational principle of Quantum HadronDynamics, an alternative
formulation of Quantum ChromoDynamics, to determine the wavefunction of valence
quarks in a baryon at a low value of Q^2. This can be used to predict the
structure function xF_3(x,Q^2) at higher values of Q^2 using the evolution
equations of perturbative QCD. This prediction is compared to the measurements
of neutrino scattering cross-section by the CDHS and CCFR experiments. The
agreement is quite good, confirming the validity of QHD as a way of studying
hadronic structure.
