The correction factors which are necessary to compare these with measurements of xF3(nu N) in neutrino-nucleon scattering are deduced and a comparison is made between the H1 and the CCFR data. A sum rule is derived for the structure function xF3(gamma-Z)measured in charged lepton scattering which is the analogue of the Gross Llewellyn-Smith sum rule for neutrino-nucleon scattering.7 pages, 1 fig.
