摘要：

We evaluate the Nachtmann moments of the nucleon structure functions from electron and muon scattering on proton and deuterium targets for 2 GeV2≤Q2≤30 GeV2. The Q2 dependence of the nonsinglet moments agrees with the predictions of asymptotic freedom only if higher-order effects are included. The Q2 dependence of the singlet moments, however, differs from simple expectations based on asymptotic freedom alone. © 1979.
